Why does Korean Air want to recruit flight attendants in China?

There are many noon routes in Korea, and many coastal cities have Korean Air branches. There are so many routes, so it’s natural that there are Chinese people to serve them. After all, if most of the passengers are Chinese and the stewardess is Korean, it will be difficult to communicate in terms of language. . The Chinese flight attendants we recruit must also be very particular about language. That's all I know. In fact, there is no need to be surprised. As I know, many of my classmates fly to Emirates Airlines or airlines from other countries.
