How to install the lamps?

It depends on what lamp you bought. Installation difficulty, whether to bring a remote control, etc.

Need an electric drill

Electric drills are usually used to install lights. Do you have it at home? Especially for heavy lamps, expansion screws are needed.

Find a master or an electrician

All the lamps you buy should have drawings. I suggest you find a master to install it in the shop selling lighting. Salary is 80- 150 yuan. Or find someone who is renovating the community and find an electrician to install it; Electricians in residential properties, if they have not installed complicated lights, had better not look for them.
