A term in Cantonese Chinese meaning "drinking tea", refers to the custom of eating tiny servings of different foods while sipping some well-brewed Chinese tea in southern China. It is an integral part of the culinary culture of Hong Kong and the Guangdong Province.

Travelers on the ancient Silk Road needed a place to take a nap, so teahouses were established along the roadside. Rural farmers, exhausted after working hard in the fields, would also go to teahouses for a relaxing afternoon of tea. At first, it was considered inappropriate to combine tea with food, because people believed it would lead to excessive weight gain. People later discovered that tea can aid in digestion, so teahouse owners began adding more variety of snacks, and the tradition of dim sum evolved in Hong Kong, and most cities in Guangdong province.
