One of the major yearly exams got leaked in India last month so the BJP has been trying to suppress that news for some weeks now.
So they've launched a racism campaign against China where Indian bot accounts have "discovered" a secretive caste system in China which apparently is worse than the Indian caste system.
They're using two things to support their claims:
- Four Occupations System which has not existed for centuries
- Hukou system which is the Soviet Internal Passport system
This is just 100% cope to feel good about living in a failing state that is India.
I've heard that rural Hukous are actually more prized than urban ones because you get land rights and that its much easier to convert from rural to urban than the other way around
