Strict rules

Every morning before work he spends an hour collecting trash on the streets near his home.

After dinner, he goes to nearby restaurants and repeatedly broadcasts "Please don't litter" with a mini microphone.

Whenever he sees someone throwing rubbish on the ground he asks him or her to pick it up.

"Some of them refuse and speak to me quite rudely, but I never give up until they do," he said. "I can't count how many times I've run after a person for several streets."

Zhong had 3,000 orange T-shirts made with the words "Don't throw trash to our descendants" and distributed them to his employees, customers and relatives.

He also printed more than 5,000 leaflets with the same message, posting them on his car and, with the permission of authorities, in public areas such as parks and residential areas.

Zhong said he is embarrassed when he sees media reports about Chinese citizens throwing rubbish while traveling overseas.

"In recent years, we see more news about Chinese tourists who have been criticized for their uncivilized behavior both at home and abroad, such as littering and climbing cultural relics for photos," he said. "I feel so ashamed that I decided to be an environmental protection volunteer to implement change as well as set a good example for younger people."

In his companies, he has set up a strict punishment system for littering and wasting food. The rules apply to everyone.

One time his son, who works at one of Zhong's companies, was having lunch in the canteen.

He left his lunch at the table to meet a customer and was forced to donate 50 yuan ($7) to a public welfare program as punishment.

Starts at home

Zhong said convincing his family of the value of what he was doing had been the most difficult part of his work.

"In the eyes of my wife and daughter, what I did made them feel quite humiliated," he said. "They expressed strong opposition and refused to walk with me when I was wearing the orange T-shirt."

During a school trip organized by his daughter's school, Zhong saw some parents throwing trash at a picnic. He couldn't help himself and started blurting out his anti-littering slogans.

His daughter felt ashamed and bowed her head to avoid people's stares. But to her surprise, her classmates gave her the thumbs-up after Zhong's speech.

"My daughter told me that she felt quite proud, especially when they said her father came across as a hero who protects the earth," he said. "From then on, she changed her attitude and began to publicize environmental protection at school."

His wife also came around to his thinking and now helps him collect trash on the streets.

What makes Zhong happiest is the improved cleanliness in Yuanyang subdistrict.

The owner of a restaurant Zhong frequently visits said: "The regular customers are all familiar with the old man and they pay more attention to their environment. We also prepare more trash cans in the restaurants to avoid waste being scattered. There has been less trash both indoors and on the streets."

Zhong said he will continue doing the work for the rest of his life. "We shouldn't just think about what we can take from society, but what we can leave behind for the world."
