What kind of running script should I practice successfully after practicing nine?

Bai Jiao made great efforts to study Jiucheng Palace. It is said that the Jiucheng Palace copied by him and the original rubbings are reflected in the sun, exactly the same. When he was in his fifties, he covered the post with paper to imitate Jiucheng Palace, but his own regular script melted the serious Jiucheng Palace in Ou Yangxun very easily, with a bleak breath and Wang Xizhi's breath.

This is a good scholar who can write regular script by himself. The poor scholar drinks milk, and what grows on him is milk; We learn calligraphy to grow our own calligraphy bones, not to drink milk and grow into cows!

Bai Jiao's Calligraphy

Anyone with a discerning eye will know that Bai Jiao's regular script is rooted in Jiuchenggong Liquan Ming, but he uses it flexibly and writes it naturally.

Look at the negative examples and learn from the unsuccessful examples of Jiuchenggong, as shown below. Starting a pen and folding a pen are very similar, especially the folding pen is almost exactly the same as the black body. For the sake of harmony, I dare not give any more examples.
