It was difficult between the 1970s and 1990s.
1969 after the racial riots, the Malaysian government formulated a new economic policy, stipulating that Malays and other ethnic minorities should get certain quotas in public institutions, business and education. Then in the process of implementation, I went too far. As a result, most local Chinese got good grades in high school, but local universities refused, and only a few Chinese with the best grades could go to local universities. As a result, China society has accumulated a lot of discontent, and a large number of talents have left the country, such as Singapore, which has benefited a lot.
In 1990s, the ruling party in Malaysia won a disastrous election. In order to gain the support of China people, this administrative deviation has been corrected. So it's gone now.
