What are "ignorant girls" and "Qinghai-Tibet Plateau" cadres?

There is such a saying among the people, which seems to make sense.

Nothing among "ignorant girls" refers to cadres without party affiliation and democratic parties, while knowledge refers to intellectuals with high academic qualifications and professional titles, less to ethnic minority cadres, and women refer to female cadres. If a cadre has one or two of them, it will be valued by the organization department. If he has these four at the same time, then his chances of being promoted and used will be higher.

"Qinghai-Tibet Plateau" should refer to mainland cadres who aid Tibet. All cadres who have had experience in aiding Tibet will generally be reused when they come back.
