There is a basis for Lao Si's mouth smoking, and many fans know it. Let's popularize it here. Let more people know that the sage is the fourth brother. According to legend, the fourth brother was only seven or eight years old in his early years. On a snowy winter in the Northeast Plain, Zhao Zheng is playing with children from seven or eight ordinary families. They are playing by a small river. As ordinary children, the four chivalrous men were afraid to walk on the ice, but Xiao Si jumped on the ice without hesitation, slapped the ice on the ice, saying it was too late, and then soon, he accidentally fell into the ice hole. But fourth brother didn't even scream. Only fourth brother can have such courage at such a young age. Later, the mother of the fourth brother who came from the mahjong table heard the news and fished out four. The fourth brother trembled, and the fourth mother was distressed. She had an idea and wrapped her fourth brother in a big quilt. When I covered the hot kang, it was cold and hot, and my mouth twitched. Since then, Brother Four has left this sacred stunt. This story also tells us that martial arts is not so easy to practice, and it is not something that ordinary people can practice well. It is necessary to be savvy.
