How to add theme text to photos of public bicycles

Use text tools to add in software such as PS/Meituxiuxiu/Light and Shadow Magic Hand/Polar Photo Retouching, or in software such as Butter Camera on your mobile phone, or even in the drawing tool that comes with WINDOWS. . It's very simple. If you want special text effects, you can search for keywords such as "PS text" on Baidu to give the text different styles.

If you don't have a PS foundation, I recommend using Light and Shadow Magic Hands. There are nice text presets.
