Children's calligraphy training institutions are places to cultivate children's interest in calligraphy. There are calligraphy classes that practice brush calligraphy (such as Tian,) and calligraphy classes that practice pen calligraphy (such as Fengge calligraphy).
Generally, it takes about 30 to 50 hours to practice calligraphy in a calligraphy training institution. There are also crash courses for adults, which take about 20 to 30 hours to complete.
