'Green code'

People are required to present their "green code", an indication they are symptom-free, on a health code app on their phones and have their temperature checked at the entrance of the shopping area.

Liu, 28, came to find out which shops accept the government issued vouchers. She was pleased to see that her favorite sportswear store was among them.

"I didn't expect to see this amount of people today, but there were still far fewer people compared to what it was like before the outbreak during weekends," Liu said.

On Sunday afternoon, people had to line up in front of some Han Street shops that decided to limit the number of shoppers inside as a part of the epidemic control measures. Some shops also have been displaying epidemic control items such as masks and hand disinfectant near their entrances to attract customers. Meanwhile, majority of the restaurants in the shopping area still only offer take-out and delivery services.
