BEIJING, Dec. 24 (Xinhua) -- China has shut down or revoked the licenses of more than 13,000 illegal websites since 2015.

Wang Shengjun, vice chairman of the Standing Committee of the National People's Congress (NPC), disclosed the information when briefing lawmakers on cyberspace protection Sunday.
