In the past, traveling by plane was unimaginable for most Chinese people. Today, with the development of China's economy and the improvement of people's living standards, more and more Chinese people, including many farmers and migrant workers, can travel by air. They can fly to all major cities, and many other cities are also planning to build airports. Air services continue to improve, and there are often cheap flights. In recent years, the number of people choosing to travel by air during holidays has been increasing.
