How much is the basic salary of electric water heater industry after installation?

The one I used as Smith is a world-famous water heater, which has been used for more than 50 years! Smith's salary is not bad, the basic salary is more than 800 points, and the delivery is of course different from place to place. I ride motorcycles in some places. I'm here! The main reason is the high cost of materials. Smith's materials are generally around 300, which is the most expensive in China, so he bought a good family. If Smith does a good job, it's basically around 3000 to 4000 a month! If it is May 1 day or 1 1 day, it is usually around 5,000 to 67! Please refer to!
