A recent article on China Daily at http://usa.chinadaily.com.cn/china/2011-06/15/content_12709933.htm credited to Xinhua, explains that personal tax laws will be changed in late June of this month.
The laws come after a review of over 230,000 recommendations about what courses of action should be taken. The general public is still on the fence somewhat as they are not sure how much of an increase to taxes they are willing to shield for their government.
