Hello, landlord. Learning calligraphy at the age of 20 has advantages and disadvantages. The advantage is that the landlord is an adult and has a conceptual understanding of the strokes and structure of Chinese characters. The most nerve-racking thing is that if the landlord wants to make a living by selling words, it will take hard work, and it will not reach the level in a year or two. Suggest that the landlord find a better teacher. Starting from basic learning, don't underestimate calligraphy. It's not that easy to practice, and don't overestimate calligraphy. You still have to have one yourself.
Stable job
