China has postponed its Chang'e-7 robotic lunar mission, with authorities saying "launch conditions" were not met and that the mission can no longer be carried out within this year's planned launch window. The delay is also affecting some businesses in Wenchang, in southern China's Hainan province, where the launch was due to take place. Visitors who travelled to Wenchang hoping to witness the launch told CNA's Tan Si Hui about their disappointment and what they plan to do next.
