One bowl with two pieces

One bowl with two pieces is a term that has long been in the vernacular of Hong Kong tea culture, meaning a bowl of tea with two "delicacies to complement the tea", i.e. dim sum. In Cantonese restaurants of the past, tea was not offered in a present-day teapot but in a bowl. The dim sum was not bite-sized. Instead, quite a number of them were simply big buns, such that two of them easily filled up one's stomach. An example is chicken ball dai bao.
In modern terms, the "two pieces" normally refers to har gow and shumai. The concept has been influenced by the "bite-sized trend".
