Lao Tang said that he was originally a restaurant owner and had a good sense of smell. In the process of selling sausages, he found a saying that "good meat does not make sausages". Sausages are usually sold with low-quality meat. Lao Tang said that he started from catering, relying on quality and word of mouth from beginning to end.

From the former catering boss to the sausage vendor. He still insisted on quality and soon became the elder brother of sausage roasting in the night market. Excellent quality soon attracted loyal users for him.

At first, he wore a mask for fear of meeting acquaintances. However, to make sausages, it is inevitable to take off the mask and meet acquaintances.

Tang Jian said that when he saw acquaintances, he usually lowered his head. Once he took off his mask and was seen by an acquaintance. At that time, the other party couldn't believe it and thought they were experiencing street life. Even after explaining it many times, the other party still couldn't believe that Lao Tang, once a household name in Qingdao catering industry, really sold sausages on the street.

Later, after this incident was reported by the media, Tang Jian simply took off his mask. Tang Jian said that in fact, from his own heart, it has always been easy. The reason why I tell my own story is to encourage more people who have the same experience as him. Everyone can hold a group in spirit to keep warm, and can stand up again and start their own lives.
