Hello, Fernando. Indeed Tai Chi Chuan or Taijiquan is a Chinese martial art consisting of a very general relaxation techniques that contribute to personal well-being and health. I do not know much about the subject, but I think the current article in Wikipedia is reliable, and it appears that Manuel Joseph, the principal author is an expert in this discipline. I hope this will dispel your doubts about the veracity of the article. A salute and happy new year! – AngelRiesgo (messages) 20:50 31 dic 2005 (CET)
