He is one of the three pro-democracy lawmakers in Macau.

Earlier in December 2008, nine pro-democracy lawmakers were denied entry to Macau, where they planned to protest against Macau's version of the Article 23 laws.

The pro-democracy lawmakers walked out in protest after the defeat of the sunset provision, clearing the way for the bill's final passage.

The bill passed the 60-member Legislative Council on a vote of 32-0 after pro-democracy lawmakers walked out of the chamber in protest.

When pro-democracy lawmakers raised privacy concerns, officials shelved their more ambitious proposals for the card.

This number, however, is widely seen as too small to influence pro-democracy lawmakers.

On 21 December 2005, the reform political reform package was vetoed by the pro-democracy lawmakers.

On March 6, 2008 Wang began publicizing the need to grant 24 Home Return Permit to the pro-democracy lawmakers.

Chief Executive Donald Tsang declined to meet with pro-democracy lawmakers during the protest.

He also ruled out travelling with pro-democracy lawmakers to Beijing to speak with the central government.
