Chinaman's chance is an American idiom which means that a person has little or no chance at success, synonymous with similar idioms of improbability such as a snowball's chance in hell or when pigs fly. Although the origin of the phrase is unclear, it may refer to the historical misfortunes which were suffered by Chinese-American immigrants. The expression is controversial due to its use of the term "Chinaman".
