Because my father had a son at the age of forty, he adopted his baby name "Dog" for safety, hoping that he could nurse like a puppy. /kloc-When he was 0/4 years old, Gui Youyou went to Liu Jia Steamed Restaurant near the South Canal in Tianjin as a waiter. Because of ingenuity, diligence, and the guidance of the masters, your friends' skills in making steamed buns have been continuously improved, and they have become good at it. After three years as a teacher, Gui Guiyou opened a snack bar specializing in making steamed buns-"Deju Haohao".
