The term “acquaintance blind date” literally means “exchanging grass”， with grass referring to young men. Such events are usually initiated by “leftover women” — single women who have passed the best age for getting married. These women may bring single male friends, colleagues or relatives to a get-together and expect to find their Mr. Right among their peers’ male friends。

　　“换草运动”其实就是熟人召集的相亲会，这里的“草”指年轻男子。这种活动多数都是由大龄单身女们组织的，她们会把各自身边的男性朋友、同事或亲戚组织到一起参加聚会，希望能从对方带来的朋友中找到自己的另一半。

　　This event originates from an online post that proposed to exchange male friends or colleagues with other single women since it’s not a good idea to develop a romantic relationship in the same office。
