Longfeng (simplified Chinese: 龙凤; traditional Chinese: 龍鳳; pinyin: Lóngfèng; Wade–Giles: Lung-fêng; 16 March 1355 – January 1367) was the era name (nianhao) of Han Lin'er (Young Prince of Radiance 小明王), who was a rebel and emperor of Han Song (1355–1367) during the Yuan dynasty of China. It was used for a total of 12 years.[1] After Han Lin'er's death, his subordinate Zhu Yuanzhang, Prince of Wu, changed the next year (1367) to "Wu 1" (吳元年, "the first year of Wu"), and in 1368 (Wu 2), to "Hongwu", and established the Ming dynasty.
