not applied in the whole.country now.one more point:
The additional point is given only to a minority ethnic group student if he is a minority and lives in a minority populated place eg Tibet and Xinjiang . A minority student who has lived all his/her life in a big city like Chengdu or Beijing is not awarded the extra points in exam.
in beijing, for high school entrance this modification is said to start since 2017. for university entrance, no time line set.
in other provinces, this is applied this year(or maybe in recent two years). some places like shandong will completely remove this in 2017.
