Let's reveal the basic information. Dana is a training institution. Generally speaking, we learn more online and less offline. The offline teachers are generally, and the online ones are all big coffees, so you can only go to the training institutions by yourself.

Tuition fees in this country are set by themselves without setting corresponding standards, but this industry started in tens of thousands, so you can listen carefully, but don't set it at once. This is my personal suggestion, and I hope to adopt it.
