Over two thousand delegates across China will soon gather in Beijing to take part in the 20th National Congress of the Communist Party of China. Our reporter Zheng Songwu spoke to one of the delegates from Ganzi Tibetan Autonomous Prefecture in southwest China's Sichuan Province. 

This is Chimed Dorje, a postman delivering mail through snow-capped mountains with an average altitude of 3500 meters above sea level in Sichuan Province.

As a team leader, he speaks to his team members every morning to ensure everyone is well-prepared for the long trip. Chimed Dorje began to work as a postman in 1989, over a decade after China began its reform and opening-up policy, but even then, the remote and mountainous areas where he delivered mail were still isolated. People of his profession played a crucial role in maintaining communication between rural and urban areas.

CHIMED DORJE, Postman, Ganzi Tibetan Autonomous Prefecture "At the beginning of the reform and opening up, there were few communications between high plateau areas like Garze and the eastern urban areas, so we served as a link between them. We also delivered personal letters and money in rural areas, because some workers sent money to their families in envelopes."

Chimed Dorje and his colleagues were always ready for unexpected challenges, especially for the snow and ice in winter. He and his partners had to equip the tires with nonskid chains.

ZHENG SONGWU, Ganzi Tibetan Autonomous Prefecture "The altitude here is over 4,000 meters above sea level, Chimed Dorje delivers mail to this region by traversing a vehicle up these mountains over 300 days a year. Each trip is at least 200 kilometers."

Chimed Dorje suffers from snow blindness and has to wear sunglasses, but for him, the harshest thing has never been the bad natural conditions, but being away from his family, especially during Chinese New Year.

CHIMED DORJE, Postman, Ganzi Tibetan Autonomous Prefecture "We had a saying that there were only eagles in the sky and postmen on the roads during Chinese New Year. Others were having reunions with their families but we were on the road. But thinking about people's smiles and happiness when they received mail or necessities, made me happy too and I never quit this job."

Chimed Dorje says even though he was absent from family reunions during Chinese New Year for years, his family understood and supported him a lot, which also gave him the faith to continue the job. And over the past 33 years, he has been impressed not only by the increasing variety of packages but by the development of roads and traffic system in Ganzi Tibetan Autonomous Prefecture.

CHIMED DORJE, Postman, Ganzi Tibetan Autonomous Prefecture "There were no asphalt roads, no highways, and no tunnels. Our Party and central government supported us hugely over the past decades, now we have highways, tunnels, and airports. And our vehicles are getting bigger, from one that weighs four tons to 12 tons. I'm impressed and feel privileged to have witnessed such development."

The good traffic system now also allows Chimed Dorje to send necessities to the residents who were affected by the earthquake in September. But he and his partners still serve an important role in delivering mail to remote areas. As a delegate of the 20th CPC National Congress, he says he wants to share with other delegates about the developments in the Ganzi Tibetan Autonomous Prefecture. Zheng Songwu, CGTN, Sichuan Province.
