Different provinces have different registration fees. The biggest price difference can exceed that of 30 yuan. I put together a picture here.

Among them, the highest is 50 yuan in Chongqing, and the lowest is only 13 yuan in Shaanxi, which are generally gathered in 30 yuan above 20 yuan.

In 2009, the National Development and Reform Commission and the Ministry of Finance issued the Notice on Approving the Fees of CET-4 and CET-6 in the Education Examination Center. The examination fees of education examination institutions are as follows:

CET-4 8 yuan, CET-6 10 yuan.

But the labor, cost and division of departments all need money, so the extra money is used here. No middleman earns the difference.

In order to ensure the smooth progress of CET-4, those staff members don't order too much.
