I can help you solve this problem. I am a graffiti lover! This can be called street art, and what you said can be divided into street graffiti! Graffiti in the morning is the function of a gang religion to transmit information abroad. Now people often regard it as a trend and artistic presentation! There is a simple bomb, which is also a long-term PIC. Most of them draw their own labels, that is, their own signatures, and express their feelings of painting through the font color effect and the characters and objects drawn! Also looking for a kind of stimulation and exercise or recognition! Typing is tiring. I hope to adopt. Thank you. Happy new year.
