Dim Sum (literally meaning: touch the heart) was originally not a main meal, only a snack, and therefore only meant to touch the heart, it is now a staple of Chinese dining culture, The unique culinary art of dim sum originated with the Cantonese in southern China, who over the centuries transformed yum cha (tea drinking) from a relaxing respite to a loud and happy dining experience. In Hong Kong, and in most cities and towns in Guangdong province, many restaurants start serving dim sum as early as five in the morning. It is a tradition for the elderly to gather to eat dim sum after morning exercises. For many in southern China, yum cha is treated as a weekend family day. More traditional dim sum restaurants typically serve dim sum until mid-afternoon. However, in modern society it has become common place for restaurants to serve dim sum at dinner time, various dim sum items are even sold for take out.
