I know one, Luohe New Age Education. In Luohe Cultural Palace, they received college entrance examination training for college entrance examination art students. From February to June next year, if they fail the exam, they will get a refund. They are a national chain group education and training company. Teachers who specialize in college entrance examination art students will come down from Zhengzhou to give lectures, which is of great help to art students. I hope they can help you.
