As the xoi Thuy offers is delicious, the product sells like hot cakes. Thuy uses 100 kilograms of materials, including cassava and sticky rice, to prepare xoi san which sells out just several hours.

A video showing the woman sitting at her stall and selling xoi to passersby on Cat Cut street in Le Chan district in Hai Phong has been has attracted thousands of interactions on the internet.

In the video, the woman is seen sitting at her stall and surfing the internet, though it is raining and inundated with water. Next to her are flat baskets of hot xoi san, put on chairs to avoid the water.

Many viewers have left comments about the woman's ability to stay calm amid the flood and rain.

Thuy told VietNamNet that she was surprised when the video spread through social networks.

She said many streets in Hai Phong remained inundated several days after the Yagi typhoon. The area where her xoi san stall is located also flooded, but she still sold xoi.

In addition to xoi san, she sells other dishes made of steamed cassava. The products are priced between VND15,000 and VND20,000.

The dishes are put in separate basins on a charcoal stove to keep them hot.

As cassava is only available in season, Thuy sells xoi san for just several months, from the seventh month to the second month of lunar year.

“I start selling xoi san at 9am every day. Sometimes I start later because it takes time to process dishes from cassava,” she explained.

Thuy said she needs support from family members to maintain the xoi san stall. Four family members have to get up at 1am and work until 9am, when xoi san is ready for sale.

In order to make delicious high-quality xoi san, she only uses cassava grown on hills and special sticky rice (Glutinous Roundgrain Rice).

Customers joke that only lucky people can eat Thuy’s xoi.

“In the morning, when I leave home for the office, the stall is closed,” Thuy Linh, a customer from Le Chan district, said.
