Pu Jiayun, 23, has been a courier for more than half a year. Initially, he worked at an outlet with only four to five staff members. Now he leads a team of more than 20.

The team recently received more than 400 take-away orders as the temperature rose and people's will to go out for lunch went cold. During the peak hours in afternoon, they delivered up to 300 orders.

Pu left his hometown in Southwest China's Yunnan province at the age of 15. He had been to many places before arriving at Wuhan, capital of Central China's Hubei province. He liked the city due to the hospitality of local people.

Once he had to take the stair to reach the eighth floor of a building to deliver a meal as the elevator was not working. The customer, a man in his 30s, bowed to him when he received the meal. Whenever Pu is tired, he thinks of the experience and feels that it is worthwhile as long as the customer is satisfied.
