Shenzhou VII has only been out of the cabin for a while, what’s the significance?

I think the significance is mainly to test the outer clothing of the space capsule and provide valuable first-hand information for the future construction of the space station and landing on the moon.

China's aerospace industry is progressing step by step. Without walking outside the warehouse, there is no way to know what technical problems have not been overcome and what needs to be done to go to the moon in the future. The length of time is not important, what is important is "being able to walk". As long as this is confirmed, there is not much difference between walking for five minutes and walking for five hours, so hurry up and get down.
