First of all, there are many schools of traditional Wushu, and each school is widely circulated in this area. Different masters have different skills in inheriting this school, and individuals are good at it. So it is difficult to have a unified standard, whether it is used to define a certain genre or the standard techniques of this genre. Therefore, it is really difficult to make Wushu popular.
Secondly, traditional Wushu is a "skill" that is really used for self-defense. It's simple and practical, and it's not the so-called "martial arts" of the present performance nature. If you really have an intuitive understanding of this, you must find a folk expert with real kung fu to learn. Because it is real kung fu, and the old master is generally influenced by traditional ethics, he should not easily show his real kung fu (except when his life is threatened), but should be taught carefully. Because there is no quick method for traditional Wushu, it is expensive to practice hard overnight, and the understanding of Wushu is also improved with its own improvement. Moreover, people who learn martial arts must have good martial arts morality and know the true meaning of learning martial arts.
Thirdly, in this utilitarian era, the development and popularization of Wushu is not easy. Because the system is difficult to establish, the operability of promotion is very low. Low operability means that the return on huge investment is actually not high. In this era, no one will support anything without income, including the country. In fact, Wushu is difficult to promote because the state does not support it. Imagine a taekwondo gym making money, or asking an old master to teach. The former may achieve something in a few months, while the latter takes several years, provided that the master is willing to teach. At present, the state's attitude towards traditional Wushu is still policy support, but economic support is not. If you really want to be promoted, you need people with heart and money.
Sometimes it is fate that gives you a chance to learn martial arts.
