Are there many kinds of crosses between Tian Yingzhang and Ou Kai? I saw a nonstandard cross.

This is Tian Yingzhang's typical European writing style, and it is also the characteristic of his calligraphy. This writing method is also very easy: you don't need to start writing with the front, but you can start writing with the front and carry a pen, that is, you can start writing directly with the nib, and at the same time move the pen to the right (this writing method is also called the front), and then gently press and rotate the front to start writing when closing the pen.
