What is the name of the Chinese steamed bun filled with barbecued pork?

The Chinese steamed bun filled with barbecued pork is Char siu bao.

Char siu bao is a Cantonese baozi filled with diced char siu, the glossy, sweet-savory barbecued pork known for its roasted flavor. It is a classic dim sum item commonly served during yum cha and is also sold in Chinese bakeries. The filling is often combined with a syrupy sauce made from ingredients such as oyster sauce, hoisin sauce, sesame oil, soy sauce, sugar, and rice wine.

The traditional steamed version has a soft, white exterior. Its dough is distinctive because it commonly uses both yeast and baking powder, producing a fine, slightly dense bread-like texture. A baked version also exists; it is browned, glazed, and more bread-like.

Char siu bao is easy to confuse with xiaolongbao, but xiaolongbao is a soup dumpling typically filled with meat and broth. Shengjian bao is pan-fried rather than steamed, while zongzi is a wrapped glutinous-rice parcel, not a wheat-flour bun.
