Fenghuotongxin are the Chinese characters for ‘beacon’ and ‘communication’. A beacon, which utilizes a fire burning atop a hill or tower to send visual signals, is an ancient communication method documented as early as 781 B.C.E. in China. Ancient beacon towers are still retained on the Great Wall and in some cities.Naming citation (MPC batch dated 2018-05-29), IAU / Minor Planet Center, via NASA/JPL
