How to find a 30% discount advertising map for PS ~

I'm worried that this won't happen ... For example, if you build a new canvas with a height of 20X30 and a width of 20, and then pull the auxiliary line, you can press F8 every10cm to measure an auxiliary line with a frame. If you really can't create a new 3 mm canvas, fill it with colors and drag it. If you have measured the content of the auxiliary line, you can find a picture of the hotel from the internet and get an introduction. Put some photos of the lobby or guest room, search for the introduction and post them together.
