Chinese farmer in Pear S. Buck's novel The Good Earth, written in 1931 before Wang was more than just a Chinese name.
"And at last Wang Lung said, 'Well, and I have come for a thing and if it is not your wish, let us talk of other things. But if you have need for a servant in your great grain market, there is my second son, and a sharp one he is, but if you have no need of him, let us talk of other things.'

And Wang Lung answered proudly, 'My sons are both good scholars and they can each tell when a letter is wrongly written, and weather the wood or the water radical is right.'"
