(The course originates from the long-term development strategy of bloggers, and it is the easiest to earn millions of jobs. This course can be an introduction + improvement + reinforcement course for Xiaobai. Basically, Xiaobai takes this course, and other we media courses don't need to learn. It is also very good for people who are already small bloggers. Practical, especially if you haven't had a big hit for a while ~ it will let you quickly learn the logic of the hit.)
