回复，

Good question, but I am on a trip and can't easily type in Chinese. Hopefully, qinweijing, nanfeng, draught, gezhu, ben, laren, xinzhuangke, ymliu, etc. can give you good advice. Some of them are teaching calligraphy class right now so they may have insightful opinions for you. I suggest you post your questions in "Shui mo qing huai" group.
