    Want to be an astronaut?Then“study hard，stay healthy and have perseverance”!

    This is what Chinese astronauts Fei Junlong and Nie Haisheng said in Hong Kong．Fei，Nie and leading engineers of Shenzhou VI visited Hong Kong from November 27 to 30，2010．

    They talked with primary，secondary and college students．Kids were interested in the astronauts' space lives．They asked questions like “Did you see the Great Wall from space?”Fei and Nie said they didn't see the Great Wall．But they felt excited when they passed over China，including Taiwan．The Taiwan Island looks very beautiful，like jade．

    Young people wanted to know how the astronauts developed(发展)their careers(职业)．“How did you decide to be astronauts when China's space industry is still at the beginning?”spoke a young woman．The astronauts said it was because of their love of flight and the need of the nation．They said their love of flight could be seen from their children's names．Nie's daughter is named Nie Tianxiang，which means“flying up high”．Fei's son is called“Fei Di”，which sounds like“Feidie”，meaning UFO．
