There are two ways.

The first effect is not so good. Type and grind the skin, then type the same word and fold it in white.

The second technique is to type and copy the materials and then stack them until they become a little thick, and then stack them in white.

PS is actually very simple to type. Click the right-click blending option on the text layer in the lower right corner and stroke as follows. I know all the stupid steps.

If you still don't understand what I'm saying, I can send you a tutorial at Baidu Hi this weekend.
