Heping calligraphy daquan
This is very simple. Just ask a painter or calligrapher to help you finish it. Then cut out the word world peace, put these four words on white paper, brush the blank parts in black, and then take away the font, so that it can appear in the case of white words on a black background. This principle is the same as a red banner with white characters on a red background. You can print it out. I hope I can help you!
