Many people recommend Mo You's calligraphy online. I don't know how the learning effect is.
A parent of the parent group recommended Mo You's calligraphy to me. At first, I signed up my child with a try. I didn't expect the effect to be quite good I have studied for less than a month, and my handwriting is quite regular, and I have been praised by my teacher. Mo You calligraphy adopts online and offline teaching mode. There are live classes or offline campus classes every week. Teachers will systematically explain the word-formation rules of Chinese characters and answer questions in real time. The rest are taught online and offline.
