The ancients said: "Scholars are light and scholars are heavy; There is no first in literature, and there is no second in martial arts. " It means that although there are great disputes between martial arts schools, you will know who is the first when you come out to play a game. Masters usually stop playing, and then they admire each other and become good friends! However, the arguments between scholars are relatively close, so because each faction holds its own words, no one refuses to accept anyone, and finally it ends in discord! Real masters prefer to understand other people's ideas rather than be their own spokesmen.
