Happy New Year!

New Year’s Day is celebrated with great enthusiasm as a time for fresh beginnings: resolutions, hopes, and promises of transformation, with 365 days of potential stretching ahead. Yet, if we pause to reflect, isn’t New Year’s Day just like any other day? Every morning brings 24 brand-new hours, brimming with possibility, no matter the date. So why reserve this sense of renewal for only one day a year?

Imagine waking up every morning with the same excitement and resolve that accompanies January 1st. Each sunrise offers an opportunity, set tasks, and make progress toward a life filled with purpose and creativity. Treating every day as a new beginning allows us to release the weight of yesterday’s mistakes and fully embrace the present moment with hope.

Bill Gates once remarked, "Most people overestimate what they can do in one year and underestimate what they can do in ten years."

This insight sheds light on why many ambitious goals remain unfulfilled. 10 years may seem distant, but each day is what we have now, offering a chance to move closer to our dreams.

The true challenge lies in showing up with each sunrise, taking solid steps forward, and overcoming the inertia or distractions that each day brings.

As we begin a new year, here are a few tips to make this time of renewal meaningful:  

1. Big goals are built on small, daily steps. Dreams only materialize when anchored in consistent effort.  

2. See your dreams in daily actions. Discipline is the bridge between vision and reality.  

3. Break goals into manageable tasks. Think of each day as a building block toward your larger ambitions.  

4. Celebrate small wins. Acknowledging progress, however modest, helps sustain motivation and makes the journey more rewarding.

Often good news does not arrive with loud gongs and drums but flows in quietly like deep waters.

Finally, I’d like to share a lesson from this Chinese saying, and I hope you find it meaningful as well:

“不积跬步，无以至千里；不积小流，无以成江海.” (Bù jī kuǐ bù, wú yǐ zhì qiān lǐ; bù jī xiǎo liú, wú yǐ chéng jiāng hǎi)

“Without accumulating small steps, one cannot reach a thousand-mile goal; without gathering small streams, a river or sea cannot take form.”

This ancient proverb reminds us that achieving great goals requires consistent, incremental effort. It echoes the idea of treating each day as an opportunity to take small, meaningful steps toward a larger dream.

12/31/2024 Today marks the final day of 2024. Each year, I encourage my children, my students, and myself to reflect on the past while envisioning the future—a tradition instilled in me by my father. He believed that looking back gives clarity to the paths we've traveled, while looking forward inspires purpose for the journey ahead.

As I sit down to write, I can’t help but review the monumental events that defined this year. Though I personally may not have reached any milestones, the world has experienced a whirlwind of change.

In the United States, a historic political comeback saw Donald Trump return to power, reshaping the American political landscape. Meanwhile, the Gaza Strip remains engulfed in suffering and massive life losses, as relentless Israel bombings continue to devastate the land. The war in Ukraine entered its bloody third year with no end in sight, a grim reminder of the valuable peace that we so enjoy.

On a brighter note, China witnessed extraordinary advancements, particularly in the electric vehicle (EV) sector. EV adoption surged, positioning the nation far ahead of Western markets and signaling its leadership in electrification and clean energy innovation.

I used to read widely on social media, immersing myself in current events and hot topics like Trump, American politics, policies on China, and cultural trends. However, much of the content about China today leans negative. Now, with a renewed sense of mission, I am focusing on different narratives—stories that highlight China’s progress and vision.  

Two days ago, I came across an article about the long-awaited "Construction of China-Kyrgyzstan-Uzbekistan Railway to begin on December 27."  

The China-Kyrgyzstan-Uzbekistan (CKU) Railway (中吉乌铁路, Zhōng-Jí-Wū Tiělù) Project is a monumental infrastructure initiative in Central Asia that has been in the making since 1997.

This railway is a critical part of China’s Belt and Road Initiative (BRI) and represents a significant step forward in fostering connectivity between East Asia, Central Asia, and beyond.

The railway begins in China’s Xinjiang Uygur Autonomous Region, crosses into Kyrgyzstan’s mountainous terrain, and extends into Uzbekistan. Eventually, it will connect with existing rail corridors leading to Europe and the Middle East. Spanning approximately 310–373 miles, the railway will traverse some of the most challenging terrain in Central Asia, requiring sophisticated engineering to address high altitudes, seismic activity, and the construction of tunnels and bridges.

Why Is It a HUGE Deal?

1. Shorter Trade Routes:  The CKU Railway reduces the travel distance for goods moving between China and Europe by roughly 900 kilometers, offering a faster and more cost-effective alternative to routes through Kazakhstan and Russia.

2. Economic Opportunities for Kyrgyzstan and Uzbekistan:  For these Central Asian countries, particularly Kyrgyzstan, the railway promises significant economic benefits. It will create jobs, enhance trade, attract investment, and stimulate local industries, while also improving their infrastructure.

3. Strengthening Regional Connectivity:  The CKU Railway integrates Central Asia into the global trade network, fostering stronger ties between neighboring countries. For China, it aligns with efforts to diversify trade routes and reduce reliance on existing corridors.

4. Geopolitical Implications:  The railway shifts regional dynamics by offering alternatives to routes traditionally dominated by Russia. It reinforces China’s strategic presence in Central Asia, a region historically under Russian influence, enhancing its role as a major player in global trade and geopolitics.

A Vision Inspired by the Past and Aimed at the Future

While some countries are preoccupied with war and conflict, China’s focus on building infrastructure like the CKU Railway reflects a future-oriented, far-sighted and constructive approach.

This project not only represents an engineering marvel but also serves as a powerful symbol of collaboration and progress, contributing to regional stability, economic development, and a shared vision for the future. In many ways, it carries forward the legacy of the ancient Silk Road, which for centuries served as a bridge connecting civilizations, cultures, and economies from East to West.

Like the Silk Road, which Marco Polo famously chronicled, the CKU Railway rekindles the spirit of exploration, exchange, and connectivity that defined an earlier age. Through projects like this, China is not just reviving ancient pathways but creating new ones, reinforcing a global network of shared prosperity. It is realizing an ancient dream of connecting peoples, enhancing mutual understanding, and building a world where commerce, culture, and cooperation transcend borders. China is thus crafting a legacy of connectivity, exchange, cooperation, and prosperity.

Talk about legacy at the end of the year, ever think of what legacy are you creating now?

Lately, I’ve found myself grappling with a challenge: sharing stories about China doesn’t seem as engaging to my readers as I had hoped—especially those in China. The famous words from Reagan during his 1980 debate with Carter, “There you go again,” keep echoing in my mind as I imagine readers skimming through yet another China-related piece.

Still, I feel a renewed sense of mission as we approach the new year. My plan is to focus on China stories, drawing from Western media sources whenever possible. Here in the U.S., most people, including my own children, get their "facts" almost exclusively from American mainstream media. If I don’t write, many may remain untold. Sometimes, it’s worth embracing a little self-assigned purpose, and this is mine.

Now, the real challenge is making these topics—often considered as dry or uninteresting—come alive. Here’s my latest attempt.

The Altash Water Conservancy Project: “Xinjiang’s Three Gorges Dam”

Today’s story is a big deal for local people in Xinjiang. It is the Altash Water Conservancy Project (阿尔塔什 Ā'ěr Tǎ Shí)—the largest water conservancy hub in Xinjiang. 

Location and Specifications.   The project is situated in the upper reaches of the Yarkant River, deep in the Kunlun Mountains, within the Xinjiang Uygur Autonomous Region. It lies about 250 miles east of the China-Kyrgyzstan border. 

- Key Figures:

Located in a geopolitically sensitive area near international borders, it plays a role in boosting regional stability and national security.

6. Poverty Alleviation and Economic Growth   The project creates jobs, supports local industries, and improves access to essential resources like water and electricity. These developments help lift communities out of poverty and contribute to the long-term prosperity of historically underdeveloped regions.

Overcoming Engineering Challenges

The Altash Water Conservancy Project is a testament to human ingenuity, determination and resilience, given the significant hurdles involved in its construction:

- Geographic and Climatic Challenges: The remote and rugged terrain, coupled with temperature extremes, required innovative logistical and engineering solutions.  

- Seismic Considerations: Located in a seismically active area, the dam was designed to withstand potential earthquakes, ensuring safety and durability.  

- Balancing Multiple Goals: The project had to reconcile its flood-control, irrigation, hydropower, and ecological objectives without compromising any of them.  

Despite these formidable challenges, the dam stands as a monumental achievement, comparable in its transformative potential to the iconic Three Gorges Dam. For the local people, it means far more than a feat of engineering—it represents hope, security, and opportunity for development. Its completion highlights not only the expertise and determination of those who built it but also a vision for a better future, bringing stability, opportunity, and improved livelihoods to communities in one of China’s most challenging and remote regions.
