Is it a scam to practice calligraphy in East China for five days?

I'm not sure if the five-day training in East China is a scam, because I don't have enough evidence to prove it. However, I can tell you that it is very difficult to learn any skills in five days, because it takes time and energy to learn skills. If you want to learn calligraphy, I suggest you find a reliable school or coach, which can provide more comprehensive and effective training. In addition, you can also improve your calligraphy level through your own efforts and practice.
