# Mengjin, Luoyang

Mengjin District is a district in Luoyang City, in the northwest of Henan province, China, located to the north of Luoyang's urban districts.

## History

Mengjin began its life as an ancient ferry crossing for the Yellow River. According to legend, King Wu of Zhou crossed the Yellow River at this location, after forming an alliance with the other nobles, leading to the theory that the original name was actually (盟津; Méngjīn; 'ferry crossing of the alliance') rather than 孟津; Mèngjīn. According to this theory, it was only in later times that the character 盟 was mistakenly replaced by 孟. The ferry crossing was an important strategic location during times of war.
In Chapter 6 of Romance of the Three Kingdoms, Cao Cao explains that part of his strategy in engaging Dong Zhuo's forces was for Yuan Shao's forces to take control of Mengjin (see: Battle of Xingyang).
As of 2012, Mengjin is divided to 10 towns. In March 2021, Jili District was merged into Mengjin District.
