First, Yaocheng cost
There are many people working on the cost of Yaocheng, but it is difficult to use the drawings in depth. One teacher for each major takes the whole course, paying more attention to the practical difficulties, and more like an old master's teaching experience!
Advantages: There are more dry goods.
Second, the cost of firewood and gas
Chai Qi's cost, once a cost teacher, is very famous in the school. Teacher Chai's lecture on theory is full of strength and loud voice. Other teachers talked about the software and knew the drawings. Better theory, more car-scrapping!
Advantages: Good reputation.
Third, the gorgeous cost.
Gorgeous cost, theory and software are all brought by different teachers. The drawings are simple, the geographical location is good, the lobby is crowded, the atmosphere is good and the publicity is good! Suitable for students!
Advantages: Good geographical location.
I feel after listening to the above, but I don't know much about the latter.
