An elm tree witnesses China's space missions

      There is an old elm tree only 50 meters away from the launch pad of the Jiuquan Satellite Launch Center. Every time a launch takes place, its leaves are burned to a crisp by the high temperatures from the rocket's flames. But this peculiar tree has recovered many times, and has been a witness of Chinese space launches for the past 25 years. CGTN's Wu Lei explains the spiritual meaning found within this elm tree.
