As evening sets in, Chung Chia-ming arrives at the teeming night market of Nan'an district in Southwest China's Chongqing municipality, parks his car on the roadside, unlocks the tastefully adorned car trunk, and kicks up his mobile lemon tea stall.

Chung hails from Macao and he runs the tea stall with his girlfriend, where they also sell Hong Kong and Macao snacks.

"Customer flow has increased dramatically since the Chinese Lunar New Year. I am very optimistic about business prospects this year," Chung said, adding that he once sold more than 200 cups of lemon tea in a single evening.

"The car trunk shop is a special feature of our night market, providing a fast and efficient service to the customers," said Xiong Yingdong, who is in charge of the night market.

Chen Miao, who used to teach yoga, now runs a stall selling hand-made glutinous rice balls.

"The fitness industry had been hit hard by the COVID-19 epidemic in recent years. I was unemployed for some time and was uncertain about the future," Chen said, adding that after considering numerous options, she finally decided to launch the glutinous rice ball stall at the night market at a relatively low cost.
