What is the salary of HR in Shenzhen?

The HR grade differentiation in Shenzhen is quite serious. Generally speaking, there are about 2800 human resources experts and recruitment experts outside the customs, especially in production enterprises. But the HR of foreign companies is much higher. As far as I know, the average monthly salary of HR in customs is about 3200, and that of foreign-funded enterprises can reach 3800, which is still the most basic HR. If it is a supervisor or manager level, it is easy to achieve a monthly salary of 8000. The HR salary in Shenzhen real estate industry is very high. The monthly salary of an HR supervisor is about 6,500 yuan, and the annual salary of a manager is 1.8 million, which is almost the same. I am poor and a grassroots, with a monthly salary of about 3,400, which basically belongs to the moonlight clan.
