(Clearwisdom.net on April 30) On April 26, 2003, practitioners from St. Louis, Missouri participated in the annual "Earth Day" activity held in Senlin Park. A Falun Dafa booth and the peaceful Falun Dafa exercises attracted many people, who requested Dafa materials and information about practice sites.

Some people learned to practice the exercises on the spot. The practitioners explained to tourists about Jiang regime's crimes of persecuting Falun Dafa. Many people signed their names on the petition to call for the release of American citizen Charles Li and all other Falun Gong practitioners who are being illegally detained.
