During the Travel Rush, most people take trains when heading back home. China's high-speed bullet trains are trying to provide a better service for travelers. Not just by installing wi-fi services and other amenities, but also, for the first time, providing meals delivered from local restaurants, to the seats of passengers. CGTN's Han Peng finds out more.

HAN PENG ON THE BULLET TRAIN APPROACHING NANJING "If you are traveling from Shanghai to Beijing, and you suddenly have a craving for the famous Nanjing duck — just take out your mobile phone, and the food could be in your hands in just about an hour."

Open China's train booking app 12306, and passengers can now order local cuisine cooked by local chefs at a local restaurant, an hour before the train stops at the city. Time to say goodbye to the expensive, and often, not so delicious meals on the train.

HAN PENG ON THE BULLET TRAIN APPROACHING NANJING "Here is the Nanjing duck I just ordered on the train. And it's still hot. During the Spring Festival Travel Rush, the largest human migration on earth every year, the number of orders have exploded, straining the fast delivery service which just started half a year ago."

The moment I made the order, the clock began ticking at this restaurant near the Nanjing railway station. 60 minutes left before bringing the food to passengers -- it's literally a race against the world's fastest train. And it's a relay race. The restaurant's kitchen is the first runner.

ZHU PU RESTAURANT SALES MANAGER "This place used to be our dining area, but we transformed it into a central kitchen for the fast delivery service. Although we cancelled several tables, we believe we can make more sales by getting a lot more tables on the trains."

Then their couriers carry the food to the railway station, where all of the local orders gather before the last mile delivery.

Now, 35 minutes left before the train arrives. In the Nanjing South station, the train only stops for two minutes.

ZENG ZHAOMING NANJING SOUTH STATION "The food arrives in our office packed in different cases according to the restaurants, but when they leave for the platform, they are packed in different cases sorted out by train numbers."

5 minutes for re-packaging, then it's the turn for delivery folks like Luo Deyong to run. He's the last in the relay -- bringing the food from the station to the train. Each day, he runs the same journey at least 20 times. Good news for him: The train has not arrived as he reaches the ticket checking entry. Moving in from a special corridor, Deyong arrives at the platform, a few minutes before the train.

LUO DEYONG BULLET TRAIN'S FAST DELIVERY PERSON "The train waits for no one. If we are late by even one minute, it means passengers will miss the meal. And we must pay the money back."

But Deyong says even if the passengers get the refund, it's still not a pleasant experience for missing a meal they've waited an hour for. He gives all the orders to the train attendants, who will later bring the food to the seat of the passengers, including mine. No time for greetings, before the train roars on towards Beijing. In about two hours, it will reach Tianjin, a northern Chinese city proud of many local snacks. I ordered the most famous one.

HAN PENG ON THE BULLET TRAIN APPROACHING NANJING "Here's famous Tianjin mahua, or the Chinese twisted donuts. My duck is still even hot at the moment. With the Chinese fast-speed bullet train, plus the fast delivery service, you can literally take a bite of the entire China within just hours. And journey to home has become a bit more tasty than used to be. Han Peng, CGTN, on the bullet train to Beijing.
