When did the 9-year compulsory education begin to be free?
In 2006. China began to implement nine-year compulsory education from 1986, but it was not completely free at first. The policy at that time was to gradually implement free education until 2006. Until 2006, the government of China officially announced the full implementation of the nine-year compulsory education free policy to ensure that every student can receive nine-year basic education free of charge.
