Practice calligraphy and ask for expert advice.

In fact, you don't have to use calligraphy fonts to write posters and notices. This is not a formal calligraphy work. Others may write ordinary regular script and running script, just like the fonts typed in the computer, you can never tell which copybook it comes from. Maybe the people who wrote posters and notices have never studied calligraphy. I personally think that posters and notices can also be written in calligraphy. What you said is very difficult. I'm not sure where the difficulty lies. However, this can show that you have forgotten that you are not home yet and are not skilled, so these characteristics of Wang Ti will not be shown in your own creation. Practice makes perfect. I suggest practicing more, not only more but also better, and observing the characteristics of fonts with your heart. And your Weibei should have been able to apply what he has learned. As for those calligraphers, their fonts have their own characteristics and personalities, but there must be something passed down from ancient posts in these works, but we don't necessarily know it. Their self-creation is also based on their familiarity with copybooks. So practice more ~
