Where is the computer room of Dongguan High School?

There is no best, only the right one. You can look at the whole country and choose a school. When choosing a school, you should know more about the basic situation of the school.

I suggest you don't choose a school that rents office buildings. In fact, it can't be called a school at all, but a training class or training institution. There are often pictures in TV news newspapers that a school-running person has gone to the empty building and the tuition fees of students have been swept away. This kind of place has no guarantee for students, which is terrible.

Whether you can recommend employment after graduation, it is best to choose a school that signed an employment agreement when entering school.
