Canton-born American horticulturalist Lue Gim Gong (1860-1925) is little known to his native fellows in China, while in Florida where he lived for decades and died, he is remembered for cultivating a sweet and frost-tolerant variety of orange. His contributions to the orange growing industry were also acknowledged outside the US, when the orange species he developed were featured on a stamp issued in Israel, in 1956.

The stamp, together with a copy of a US magazine article published in memory of Lue in the 1960s, is on show at a Beijing exhibition reviewing the immigration history of the Chinese.
