195 1 year, Sir Hugh Beaver, the executive director of British kiness Beer Company, missed a golden pheasant. He complained that it was the fastest bird in the world. But his companion disagreed and had an argument with him. Sir Hugh realized that people often encounter such problems in bars. If a book can provide an answer to this argument, it will not only help people find the basis for bragging, but also help people get drunk and sell more wine.

So he decided to publish a book by his own company to record this "best in the world". Guinness World Records is far more famous than its original stout. Guinness World Records is a successful idea of Guinness Beer Company, aiming at enhancing the popularity of Guinness brand.
