It is said in novels and plays that Luo Cheng is a literati, and the so-called folk Luo Cheng is Luo Shixin in history.
The Book of the New Tang Dynasty says that Luo Shixin was born in Licheng, Jizhou. Fourteen years old in Ji Jun, guarding Zhang Xu, dragging his men to lead the troops to fight. He is very brave. Later, he returned to Shi Biao and worked in Wang. Later, he voted for Tang Gaozu in Tang Gaozu, made many meritorious deeds, and was named lord protector. In the fifth year of Wude, Luo Shixin and Li Qin ruled Liu Shimin Heilu and defended Luoshui. Liu Heita besieged city, just as it was snowing all over the world, it was alone, and the city was ruined. Luo Shixin died at the age of 28. According to historical records, Luo Shixin was "trapped in the city and died unyielding". Whether an arrow shot through the chest and died in the mud river is a folklore remains to be verified. But McCullough died in Mingshui, and the opinion is the same. According to Pingxiang county records, the ancient Ming River passes through Pingxiang area, and the Nihe River should be its general name or its tributary. Yongnian County, where the ancient civilization is located, is adjacent to Pingxiang. At the end of Sui Dynasty, Dou Jiande and Liu Heita both established their capitals here. Based on this, it is a fact that Luo Shixin died in Ai Village, Pingxiang County. There is still a earthen platform in the west of Ai Village, which is said to be the podium built by McCullough during the war with Liu Heita. Two or three miles south of Taitung is the old road of Nihe River. Nowadays, there is a barren land with heavy alkali in the cultivated land of Ai Village No.7 Team, which is said to be the place where Luo Chengyun's salt fleet capsized. According to the New Tang Book, Luo Shixin was buried in Beimang, Luoyang. Why is there a tomb of Luo Cheng in Ai Village? At that time, the war was in full swing and the general died in the army. It is normal for him to be buried in the local area first, and then moved and buried formally the next day. Therefore, Ai Village Luocheng may be the tomb of the first burial place in Luo Shixin.
