Why label Yang Teh-chi as a tiger like general in the First Field Army? Yang led the 19th Army Corps and marched into the Great Northwest after the Battle of Beiping/Tienching. Ho Lung led a Army Coprs and marched into Great Southwest and liberated Changtu. Did Ho belong to Second Field Army? During the Liberation War, Yang was always under Nie Rung-chun in Norh China.
