Luo Shixin (about 600-622), a native of Licheng (now Jinan, Shandong Province), was a famous soldier in the late Sui and early Tang Dynasties.
Luo Shixin was originally the ministry of Zhang Xutuo in charge of Qixian County in Sui Dynasty. After conquering the peasant uprising army with him, he surrendered to the Wagang army and was awarded the post of general manager. When fighting with the king, he was seriously injured and captured. Later, because he was not ashamed of the king, he led troops to the Tang Dynasty and was worshipped as the chief officer of Shanzhou Road. He stabbed Wang Xuan, outwitted his daughter's castle, and together with Li Shimin, he pacified Luoyang and became the general manager of Jiangzhou and the Lord protector.
In the fifth year of Wude (622), Luo Shixin was captured in the battle of Mianshui, killed by Liu Heita, and posthumous title was buried in Beimang Mountain forever.
