Hebei is also a coastal province. Why did people from Hebei emigrate overseas in history?

Although Hebei has a place near the sea, on the whole, Hebei is still dominated by inland farming culture. Under the farming culture, as long as people can eat enough and starve to death, people will not risk their lives and leave their homes for overseas.

Most of Hebei is in the North China Plain, so it is possible to make a living by farming. Therefore, in the past, the mobility of Jiangbei people was not very strong, and even fewer people emigrated overseas.
