China's top legislative body's supervision over law enforcement and government work is not a formality, a spokesperson said Friday.

The National People's Congress (NPC) has been improving and innovating its supervision and will continue to make efforts to prompt positive changes, said Fu Ying, spokeswoman for the Fourth Session of the 12th NPC, at a press conference.

The NPC has formed an effective supervision chain that combines law enforcement examination and special inquiries, Fu said.

Fu said legislators conducted law enforcement supervision on six laws, including vocational education law last year, and pushed forward measures that led to practical improvement after discussions with government agencies.

"The supervision will not stop until we see good results," Fu said.
