In the busiest civil aviation hub in the midwest region of China, in the terminal building Chengdu Shuangliu International Airport, the strong cold wind blowing from the central air-conditioning outlet found up high on the ceiling no longer had any force when it reached the ground, yet it still managed to keep the hot and humid air waves exclusive to the Summer in Western Sichuan outside of the door of the airport terminal.
At the airport's spacious gate, from time to time, groups of three to five passengers, or even twenty to thirty passengers, would pull their baggages and rush into the airport terminal anxiously, completely drenched in sweat.
When the cold wind hit them, most of them would breathe a long sigh of relief, with their expressions turning calm inadvertently. Of course, a small number of guests who came late for their boarding time would not be like that.
