阅读理解。 CHENGDU-After flying for five minutes over Wenchuan, Li Xiang finally found a landing place for his helicopter (直升机) on a hill near the earthquake-hit county. Li, an officer of the Aviation Regiment (陆航团) of the Ghengdu Military Area Command, then made a soft landing and waited as his team got off food and medicine while the people around cried, 'Thank you, soldiers!
