What about the glass sales industry, salary?

Not bad. The income of the glass sales industry itself is relatively high. People can buy various types of glass through legal channels and sell them to customers, thus making a profit. There are also many service fees or assembly fees in the income of the glass sales industry, and some of them can even exceed the income of simple installation, so the salary of the glass sales industry is ok. The glass sales industry still has some great development potential, and the remuneration of this industry is also relatively rich.
