1, Aozao noodle restaurant was originally a small shop under Yufeng Mountain in Kunshan during Tongzhi period of Qing Dynasty. Due to poor management, it changed hands several times and fell into the hands of a young woman, Yan. Under her careful management, she developed a kind of red oil noodles with white soup and red face, named "Aozao", which means everything is sloppy in Wu dialect.

Anyone who is happy in Kunshan will invite him to eat delicious Ozao noodles in a very special way. The parties go to the store to buy a face ticket with the word "Xi" written on it and give it to relatives and friends.
