images not displaying in about.md

[logan14925]

Hello, guys. It confused me a lot that my images could not be displayed in about.md(https://logan14925.github.io/Jiacheng_Xue.github.io/). It is interesting that in another page(https://logan14925.github.io/Jiacheng_Xue.github.io/favors/), the images showed well, and I wrote the code at the same way.

I confirmed that path is correct and in md preview section(VsCode), images could be well displayed.

Could you help me solve this issue?I'd appreciate it a lot.
