On the plane.
Zhang Ye was sending voice messages to his mother while preparing to board the plane. His conversation to her was so funny that the people around him were nearly cramping up with laughter. They heard him saying, "Aiyo, Mum, you don't have to worry at all. I'm just going on a trip abroad; nothing could possibly happen. Rest assured that I'll abide by the principles of respect and tolerance on my trip this time. If they don't respect me? Then I will still respect them. If they still disrespect me? I will still respect them. If they still continue disrespecting me? I will still continue respecting them? And if they still insist on disrespecting me? Then dammit, I'll friggin' take it up with them—they can't keep on disrespecting me, don't you think?"
Ning Lan laughed. "Hahahahaha!"
Xiaodong laughed. "Hahahahahaha."
Xu Meilan also couldn't hold in her laughter anymore.
