I lived in China for a couple of years when I came back my friends wanted to go eat japanese food. It was so surprising to me to go to the japanese resturant for a change and hear the waitresses and cooks speaking solely mandarin. I asked them about it. They said "People want to pay as little as possible for chinese food, but they pay more for japanese food." So when their Chinese resturant wasn’t making enough money they reopened as a japanese resturant.
