Ye Gaungfu, 36, is one of China's second-generation astronauts. He was talking with China Daily reporter Zhao Lei in Yantai, Shandong province, after he took part in a sea survival training session.

We have participated in survival training in pools and reservoirs, but this is the first time we followed such training at sea.

The sea survival training was very realistic. For example, we were asked to check whether we are able to perform the proper maneuvers and procedures in strong waves, and if the waves were not strong enough, several ships would be sent to sail back and forth around our boats to generate stronger movement.
