Synopsis

Baozi is the most popular traditional Chinese steamed bun, made by wrapping various fillings in fermented dough and steaming them. Legend has it that Zhuge Liang invented baozi as an offering during his southern expedition. Goubuli Baozi, Xiaolongbao, and Char Siu Bao are the three most famous types. Baozi flavors vary widely across China, with Tianjin’s Goubuli, Shanghai’s Shengjianbao, Guangdong’s Char Siu Bao, and Hangzhou’s Xiaolongbao each having their own distinct characteristics. Baozi is the soul food of Chinese breakfast, and steaming bamboo baskets are the most common sight on early morning streets.

Overview

Baozi is one of the most popular traditional Chinese wheat foods. It is made by wrapping various fillings in leavened dough and steaming them in bamboo baskets. Baozi have a white, plump, soft, and fluffy exterior, revealing a savory and juicy filling when bitten into. A steaming hot baozi paired with a bowl of soy milk or congee is the most classic and everyday breakfast combination for Chinese people. From the pork and scallion buns of the north to the crab roe soup dumplings (Xiaolongbao) of the south, from Tianjin's Goubuli to Guangdong's Char Siu Bao, baozi accompany Chinese breakfast tables in countless forms.

The English terms "Baozi" or "Steamed Bun" are becoming increasingly familiar to Westerners. With the global popularity of Chinese dim sum, baozi are moving from Chinatowns to dining tables worldwide—creative versions can now be found in upscale restaurants in New York, London, and Paris.

Historical Origins

There is a widely circulated legend about the origin of baozi. During the Three Kingdoms period, Zhuge Liang led his army on a southern expedition against Meng Huo. When crossing the Lu River, local customs required a human head as a sacrifice to the river god. Unwilling to take a life, Zhuge Liang ordered his soldiers to wrap beef and lamb filling in dough, shaping it into the form of a human head as an offering, calling it "Manshou" (barbarian's head). Later, "Manshou" gradually evolved into "Mantou," and eventually, the stuffed version became known as "Baozi," while the unstuffed version retained the name "Mantou."

By the Song Dynasty, baozi had become a common food in cities. The Eastern Capital: A Dream of Splendor from the Song Dynasty records various names for baozi—Taixue Mantou, venison baozi, crab meat baozi, etc. During the Ming and Qing dynasties, baozi developed rich and diverse regional characteristics across the country.

Tianjin's Goubuli Baozi is China's most famous baozi brand. Founded in 1858, its founder Gao Guiyou had the childhood nickname "Gouzi" (dog). Because his business was so good he was too busy to talk to customers, they joked that "Gouzi sells baozi and ignores people," hence the name "Goubuli" (dog doesn't pay attention). Authentic Goubuli baozi each have exactly 18 pleats, evenly spaced, resembling a white chrysanthemum.

Guangdong's Char Siu Bao is the soul of Cantonese dim sum. The filling consists of diced char siu (barbecued pork) marinated in soy sauce, oyster sauce, and sugar, creating a perfect sweet-salty flavor. The bun's skin naturally splits open during steaming, revealing the dark brown char siu filling inside, earning it the nickname "laughing mouth" or "smiling bun." In Guangdong, Char Siu Bao, along with Har Gow (shrimp dumplings), Siu Mai (pork and shrimp dumplings), and Egg Tarts, are known as the "Four Heavenly Kings of Dim Sum."

The fillings for baozi are endlessly varied.

A top-quality Xiaolongbao has skin so thin it's almost translucent, encasing piping hot soup. When eating, one must first bite a small hole in the bottom to sip the soup before consuming the rest.

Cultural Significance

Baozi hold a warm meaning in Chinese culture. Steaming hot baozi symbolize home and the vibrancy of daily life. In northern Chinese winters, the sight of steam rising from street-side bamboo baskets in the early morning, with people queuing for freshly steamed baozi, is one of the most vivid scenes of everyday life. The round shape of baozi also symbolizes reunion and happiness.
