The Origin of Tai Chi (Taijiquan) by Master Chen Bing
In March 2007, the Chinese Folk Literature and Art Association named Wenxian County, Jiaozuo City, Henan Province as the birthplace of Chinese Taijiquan.
In August 2007, the National Wushu Department conducted further detailed investigations and demonstrations on various social statements. And they named Wenxian County Chenjiagou as the "the birthplace of Chinese martial arts Taijiquan".
It is because currently there is no debate of the origin of Tai Chi in China after the official announement of the origin of Tai Chi in 2007, but still there is debate outside China due to lack of information.
Wikipedia in English about the origin of Tai Chi must be updated as in its Chinese version in order to provide correct information.
