Over the past 36 years, he has made more than 600,000 deliveries, an average of 50 per day.

For his commitment, Wang has won a number of honorary titles at national and provincial levels.

"I am a member of the Communist Party of China, and serving the people is the pledge I made when joining the Party. I am ready to live up to my oath," Wang said.

"Now, our country is developing very well. Without the Party, today's China would not exist. We have no reason not to work hard and do our part for a brighter future for the motherland."

Wang still remembers the day when his father, who was a farmer, encouraged him to leave the mountains after he graduated from middle school, telling him that he should not till fields during his "next life". So at the age of 19, he started working as a postman instead.

Before he fell ill, he worked 12 hours day, six days a week.

"Wang took his duty extremely seriously. As long as the customers required it, he delivered mail, even at night," co-worker He Chunrui said.

Wang said that he knew how important some mail was and didn't want to trouble recipients through a dereliction of duty.

He insisted on delivering mail as soon as possible, and anything he received had to be sent on the same day, no matter how tired he was, because putting off deliveries until the next day made him feel uncomfortable. Wang's motto is "Don't put off till tomorrow what should be done today".
