$BTC The secondary vocational schools in the 1980s were divided into three grades:

First grade: Finance, Banking, Justice, Public Security, Railways, Electric Power, Grain, Postal and Telecommunications, Commerce, Industrial Instrumentation Schools.

Second grade: Statistics, Supply and Marketing, Chemical Engineering, Metallurgy, Building Materials, Textiles, Coal, Geology, Machinery, Petroleum Schools.

Third grade: Agriculture, Forestry, Water Conservancy, Normal, Medical and Health, Meteorology, Sports, Arts Schools.

At that time, being able to enter a first-grade secondary vocational school was very impressive, and most graduates were assigned to their respective industries, enjoying good benefits. The salaries at that time were much better than local ones. Who would have thought that the restructuring in the 1990s, affecting grain, supply and marketing, shopping malls, and enterprises, caused a large number of people to be laid off and unemployed. On the contrary, most graduates from third-grade schools in agriculture, forestry, water conservancy, and health worked within the system, with stable jobs and high retirement pensions.

Truly, thirty years east of the river, thirty years west of the river!
