Recently, SEM seems to be quite popular, and many people are curious about this line. As far as I know, there seem to be only a few hotels in Kaifeng, and the excellent employment strength is not bad. Closed classes are not suitable for working people. If you want to apply, you should do it according to your own situation.

Search engine bidding has a good prospect, and there is a special shortage of talents in this field now. Good luck!
