Career
Originally from Yancheng (present-day Jianhu County) in Jiangsu Province, along with Wen Tianxiang and Zhang Shijie, he is regarded as one of the "Three heroes of the late Song dynasty". In 1256, together with Wen Tianxiang, Lu passed the imperial examination, thus becoming a "presented scholar" or jinshi, and thereafter joined the Ministry of Rites as a vice-minister. The capital of the Song dynasty at Lin"an in Guangdong fell to Mongol invaders from the north in 1276, and the five-year-old Emperor Gong was taken prisoner.
Together with Chen Yizhong, Zhang Shijie and Consort Yang, amongst others, Lu took care of the two sons of Emperor Duzong, seven-year-old Zhao Shi (赵昰) and four-year-old Zhao Bing (赵昺).
Later the same year at Fuzhou in Fujian Province, Zhao Shi was enthroned as Emperor Duanzong and began ruling under the era name "Jingyan" (景炎. Literally: "bright flame").
Emperor Duanzong appointed Lu as military advisor to the Privy Council with the task of continuing resistance to the Mongols. Lu became Left Chancellor (左丞相) and ran the government together with Zhang Shijie.
In 1279, Mongol forces led by Zhang Hongfan launched a large scale naval offensive against Song forces at Mount Ya (present-day Yamen), forcing Emperor Huaizong to flee.
During the ensuing Battle of Yamen on March 19, 1279, the entire Song army and navy were totally wiped out. When the eight-year-old Emperor Huaizong saw the outcome of the naval battle, he was shocked and slightly rebuked the disorder of his armed forces by saying "they should have coordinated their attack and fought as a unit"
With that, Lu gave the young emperor his seal, picked him up in his arms and jumped from a cliff into the sea, killing them both. Many imperial concubines and ministers also died and by July there were tens of thousands of corpses floating in the sea.
Thus ended the Southern Song Dynasty.
Lu"s descendants moved through many places before settling down in Qiangang Village (钱岗村), Conghua City, Guangdong Province. Today in Jiangmen City, Guangdong Province there stands a memorial hall to the "Three heroes of the late Song dynasty".
There is also a shrine to the three heroes in the Shuangxi District of New Taipei City, Taiwan. Built in 1868 during the reign of the Tongzhi Emperor in the Qing dynasty, the Three Loyalists Temple (三忠廟/三宗庙) is the religious center of the township.
