What is meant by the term, Chinaman, in cricket?

The term, Chinaman, denotes an off break bowled by a left-handed bowler to a right-handed batsman. The expression is said to have derived from the blower Ellis Achong, who although played for the West Indies, was actually Chinese and who practiced this kind of bowling, although he was not the first to do so. This term should not be confused with the other cricket term, Googly.
