You'd better go and see the school. Some schools are irregular, and many schools have collapsed. Ask him if he can find it online. Generally speaking, it takes 2-3 years to get a license. My buddy took the Oriental Boyi test in Wuxi, and his mother is more at ease with Baidu. She doesn't think she will collapse in the second case. After a lot of investigation, she finally chose this one. It seems that he did well in the exam soon.
