How to write the word "Qing Xiao Tang" in Liu Ti and Liu Gongquan, and how to write official script?

Liu style is delicate, suitable for writing small and medium-sized fonts, and should be written in regular script; Of course, official script should be written in big characters, with thick ink and realism, and it is best to be familiar with it and spread it by absorbing ink. I don't think a few words need to be confined to any one. It is better to integrate various schools and write your own style ... Not to mention the signature and a few lines of fine print.
