Tong Sing is the chinese equivalent of the Farmer's Almanac, not a collection of random factoids that people think are "Chinese".
He is one of those "white guys" who thinks he is an authority in Chinese culture because his wife is Chinese, but in fact he doesn't know anything beyond eating with chopsticks. Flipping through the pages, it shows how little he knows or appreciates it.
If his aim is to make fun of the Chiense stereotype, his efforts are half-baked at best. This book offends those who care about the Chinese culture, and spreads lies for those who don't.
