Yin Shixiong had asked the Cuban Air Force for a rather old helicopter. It had been produced by the former Soviet Union, but it was robust, reliable and strong. It flew at a stable speed but was quite loud. Yin Shixiong sat next to Gu Nianzhi and plugged his ears to shout, "Old Mao's things are all like this! No bells or whistles, kind of ugly, but safe and reliable!"
Gu Nianzhi's thoughts were interrupted by Yin Shixiong, so she glanced at him with a slight pout.
"What is it? Look at your mouth, you're pouting like a fish." Yin Shixiong tapped her lips, asking curiously, "Hmm? How come you're injured? Who bit you?"
