Chinese Cherry cultivation began in 1870s and was brought in by missionaries and overseas Chinese at that time. According to the 1915 fruit tree of Manchuria, in 1915, the American missionary J.L.Nevius brought in the first 10 varieties of sweet cherry seedlings, sour cherry and hybrid cherry seedlings, and planted them in the southeast mountain of Yantai, Shandong.
