How do you know when the time is up in the self-study classroom?

Depending on the specific study room, there may be text message reminders or someone may remind you.

Some are paid, and someone will always remind you, otherwise the merchant will lose money.

When opening a self-study room, you must prepare a business license. It must not be used as a civilian residence, and do not be greedy for petty gains. Gradually, in some communities, once the fire protection fails, there is no way to obtain a business license. It must be a commercial residence, so when renting a house, we must consider whether it is a commercial house. To apply for a business license, first go to the local industrial and commercial bureau or government affairs hall. You can also apply through the Internet. Generally, you only need to use ID card, proof of business location, etc.
