How can I write the words well? How to change the word "Doubi"?

Writing is really a matter of great care. First of all, you must love Chinese characters in China and be interested in Chinese characters in China. Copying more is a necessary stage, especially describing block letters, which requires hard work. Pay attention to the selection of regular script fonts suitable for your own writing, such as European style, Yan style and Liu style. Find the most suitable type for your own development according to your own situation. In addition, hard work is necessary, and it is best to write Chinese characters with a pen. You can also practice writing brush calligraphy properly. Develop correct and good writing posture and habits. Chinese characters have cultural connotations. It is not easy to write Chinese characters well overnight. We should understand the culture of Chinese characters. But as long as we persevere and have confidence, we will not only improve, but also believe that with our joint efforts, we will certainly carry forward the Chinese character culture in China. I suggest you look at Si Mayan's copybook or "99 Days of Pen and Ink". Pang Zhonghua, of course. But I personally recommend Si Mayan. Pang Zhonghua's handwriting is accurate, but it's a bit rigid, and it's not fast.
