Luo Tong, son of the Tang hero Luo Cheng, is the young man most editions place behind this glittering poem. At seventeen he won the marshal's seal in a contest of arms on the drill ground and led the army north against the frontier enemy, an exploit known in storytelling as Luo Tong Sweeps the North. Then the luck turned. After he drove a princess to her death, Emperor Taizong stripped him of office, and only the pleading of the old general Cheng Yaojin won him a pardon. Early fame, a fall, a rescue: that sequence is why a poem full of gold belts still ranks middle, and why the image line speaks of change at the Dragon Gate.
