Why are all the restaurants run by the Hui people called ~ ~ Zhai, ~ ~ Shun ~ ~ Xuan?

Not necessarily absolutely.

Restaurants use many words such as Zhai, Shun and Xuan, and restaurants also use many words such as Ju, Ting and Ge. It all means elegance.

The word "Zhai" is still widely used in Muslim restaurants because it is related to Buddhism and also represents vegetarian food such as fasting and fasting eaten by Buddhist and Taoist believers.

The word "Shun" must mean "Shun"

For example, "Donglaishun" in Beijing.

The word "Xuan" means a tall and bright house.

The word "Xuan" is often used as the name of study, tea room and restaurant, such as Xuan and Laixuan.

The word "pavilion" has a casual meaning and is not very formal. For example,

Warm in winter pavilion, singing pavilion.

"Pavilion" means exquisite and compact. For example, a restaurant in the Summer Palace Park in Beijing is called "Zhichun Pavilion".
