First, personal charm. Liu Genghong was originally a good friend of Jay Chou, but he appeared in Jay Chou's MV several times without causing any sensation. However, he became very popular because of his live broadcast. One of the important reasons is that he does have some real talents. He is nearly fifty years old and has a good figure. As a fitness instructor, he can choreograph a rhythmic dance with great strength. During the live broadcast, he will repeatedly remind the audience who move with him in front of the screen that they must exercise moderately and do what they can.
Second, the seasonal advantage, when the fire broke out in Liu Genghong, was in April. This season just happened after the cold spring, and the shadow of summer gradually appeared. More and more boys and girls need to take off their thick coats and put on dresses or close-fitting clothes, which makes everyone want to get a better figure and put on their beautiful clothes before summer comes, and Liu Genghong just appears in this season. As a professional coach, he can meet everyone's needs for happy fitness.
Third, everyone's aesthetic changes. Before the Winter Olympics, most people's aesthetics still stayed in the unhealthy beauty of white, young and thin. Many girls would rather be thin than exercise, and even think those muscles are ugly. This distorted aesthetic only gradually changed after the emergence of healthy and sunny women like Gu Ailing. Many people begin to think that health is the most important beauty, and those fragile ones are just a deformed beauty. Therefore, the change of aesthetic trend has given a fitness blogger like Liu Genghong a chance to become popular.
