求翻译：Practicing Chinese martial arts requires a lot of effort. You have to be able to “stand as straight as a pine tree, sit as square as a stone, and to realize the deep meaning of the arts. Not all people who practice Chinese martial arts have a deep enough understanding of them. Some regard them only as physical movement: You move here; you hit your rival there … But my coach has tried to make me realize their underlying meaning, which has a great deal to do with one’s mental state. Gradually, I’ve come to understand that the martial arts do not only improve my physical condition, but also make me feel more confident in dealing with the world around me. Many actions of Chinese martial arts are actually based on meditation. They make the goal better fitted for each person. Other forms of exercises do not necessarily make people feel happy, but when exercising martial arts, you will become calmer and more cheerful. Such beneficial function has long been realized and treasured. Many of my American friends have benefited a lot from practicing the arts, mentally and physically.是什么意思？
