I'm Lao Wu from PCB. Well, I realized it myself. We don't sell melons here in Huang Po. . At present, apart from opposing PCB, there is no open and transparent training. What is the content of each class? The homework of each class can be viewed on the PCB. . No training institution dares to do so openly and transparently. . Good or bad, you can understand it yourself. .

This answer should be stepped on. .
