Someone has made Smith's water heater, which is the world-famous water heater that has been used for more than 50 years. Smith's salary is pretty good, with a basic salary of more than 800 points. Of course, the rules for delivering goods vary from place to place. The main reason is that the material fee is high. According to the materials, Smith's is generally around 300, which is the most expensive in China, so the ones bought are from well-off families.
