Erduoyan Fried Cake originated in the Gengzi period of Guangxu in Qing Dynasty (1892). At that time, Beimenwai Street in Tianjinwei was the thoroughfare leading to the capital, and there were the largest markets for dried and fresh fruits, leather goods and medicinal materials in the city on the east and west sides. There are many shops and customers, and many small vendors dealing in various foods are attracted to set up stalls and attract business here.

Liu Wanchun, the founder of Erduoyan Fried Cake, set up the famous Erduoyan Fried Cake in the future in Beimenwai Street, the west exit of Appraisal Street. Because the fried cake made by Liu Wanchun is fine in selection of materials, fine in production and cheap in price, it quickly stood out among peers and won the reputation of "Fried Cake Liu". During Chinese New Year holidays, birthdays and happy events, people will use the homonym of the word "cake" to take the auspicious meaning of climbing up step by step, scrambling to buy and give gifts to each other, and sometimes the sales volume can reach more than 400 kilograms a day. Because Liuji Fried Cake Shop is located next to a long and narrow "Erduoyan Hutong" on the east side of Beidaguan in Tianjin, the majority of diners said humorously, "Erduoyan fried cake there is really good", but unexpectedly, this unintentional humorous nickname became louder and louder, and the name of Erduoyan Fried Cake has continued to this day, becoming one of the three wonders of Tianjin, which is enduring and famous in China.
