There are not many calligraphy competitions held in Hangzhou, but you can participate in some national competitions. If the level is amateur, you'd better take part in some small competitions. The school is well organized, which can not only guarantee the award, but also add some credits when you graduate.
Recently, there was a competition called "National College Students' Chalk Word Contest". You can also try it, because both soft pens and hard pens are familiar. If you try something new, there may be new developments.
In short, I suggest you pay attention to calligraphy information from time to time. Recommend "China Calligraphy House" website, which is very good and has a lot of timely competition information. If you take part, there will be many new competitions every year. Especially pay attention to the information on campus, and you can participate in the competition in time. It is recommended to participate in the "National Calligraphy Competition for College Students", but the theme of this competition is different every year, so we should pay attention to it in time.
I wish you progress in calligraphy!
