""Control your oxygen consumption, otherwise, you'll suffocate." His teammate persuades him gently.
Without hesitation, Xu Shenghan asks, "How much oxygen do you have left?"
"Not much less, why?"
"Can you spare some?"
"What?" His teammate exclaims in shock.
"What do you mean, 'what'? Haven't you ever been diving? Sharing oxygen during a crisis is a pretty standard procedure, right?" Xu Shenghan retorts.
"I've gone diving, but did you actually undergo any training before going into space?" His teammate quizzes back.
"No, I didn't! Why?" Xu Shenghan answers defiantly.
At the Aerospace Center's Virtual Open Day, there is a course to simulate the training that astronauts undergo and where teachers would give lectures on some common knowledge and precautions for space missions.
But Xu Shenghan didn't attend it.
