皂角树上有狐仙
[zào jiăo shù shàng yŏu hú xiān]
'There's a fox spirit on the soapberry tree.' Fox spirits in traditional Chinese legends are usually creatures full of mysterious charm, living outside human society with powerful abilities. The soapberry tree is used here possibly just as a place marker or chosen due to its distinctive feature. So this online name shows one’s preference for folklores, longing for fairy-tale or mysterious things.
