Please optimize the Chinese display

I can’t describe it very clearly, but Chinese on Obsidian, especially large paragraphs of Chinese, can be very hard to read and have a “dirty” feeling. The readability is not high. I hope the authorities can optimize

I also looked up an article and wondered if it would help Obsidian:

Comparison of Chinese display among three software (software name in upper right corner)

Is this with all themes? I imagine this is controlled by CSS styling, so you could choose (or create!) a different theme.
