State Grid does not restrict several provinces with lighter colors.

The provinces here are northern Hebei, Henan, Jiangxi, Liaoning, Heilongjiang, Shanghai, Sichuan and Qinghai.

State Grid Hebei Electric Power Co., Ltd. clearly pointed out in the recruitment announcement of college graduates in 2023 that the color-blind weak are only allowed to apply for the second batch (county power supply companies and township power supply companies), the third batch (county power supply companies or township power supply companies) and the fourth batch (township power supply companies). Weak colors can be tested in State Grid, but only in northern Hebei, Henan, Jiangxi, Liaoning, Heilongjiang, Shanghai, Sichuan and Qinghai.
