Nippon, Dulux and other big-name latex paints have higher prices. Big brands are more fake. It is recommended to buy in a specialty store. Generally, the words "several in one" are written on the barrel. The higher the better, the more environmentally friendly this latex paint is, and the less harmful components there are. If you don't feel comfortable with latex paint, you can buy an air purifier with in addition to formaldehyde function. I bought a TCL and spent six or seven hundred dollars.
