Ni said, how far is it from home in a foreign country?

100km out of the city. This field falls into two categories.

1, within 40 km -200 km, and can't guarantee to drive home every day, with different accents, so it is the first in foreign countries.

More than 2,200 kilometers away, with different accents, I knew I was a foreigner as soon as I spoke, and I couldn't guarantee to go home every day on weekdays, so I was the second foreign country.
