歇後語辞書 app for iPhone and iPad

Xiehouyu (simplified Chinese: 歇后语; traditional Chinese: 歇後語; pinyin: xiēhòuyǔ "a saying with the latter-part suspended") is a kind of Chinese proverb consisting of two elements: the former segment presents a novel scenario while the latter provides the rationale thereof. One would often only state the first part, expecting the listener to know the second. Compare English "a stitch in time (saves nine)" or "a bird in the hand (is worth two in the bush)".
Pun is sometimes invoked in a xiehouyu, thus a xiehouyu in one dialect can be unintelligible to a listener speaking another. Valuable linguistic data can sometimes be gleaned from ancient xiehouyu.
