I asked each if [Yao Xingtong and Zhang Lanxin] was afraid of heights. Each said no, and although they had never had the action movie experience they were willing to be trained. Then I asked if they could swim, and each said yes, but she (gestures toward YX) is better. She said, I can also dive, in fact I once won a diving championship in an international competition. Then she said, "But big brother, I'm not very strong," and I said that's all right.
