The reason why Japanese was once popular in Liaoning.

Through population dilution and assimilation of Northeast China. 193 1 When the September 18th Incident broke out, the Japanese army set foot in China and occupied the three northeastern provinces within three months. From then on, it began to colonize the three northeastern provinces 14 years: it supported Puyi, the last emperor of the Qing Dynasty (established in 1932), to establish the puppet Manchukuo regime, with the intention of taking the Northeast as its own through peaceful evolution. Militarily, it exercised absolute rule over the Northeast, and immigrants invaded, and as many as 300,000 people immigrated to the Northeast. It is hoped that through population dilution and assimilation, a large number of resources such as money, minerals and military industry will be plundered from the northeast, and Japanese education will be promoted in the northeast to assimilate culturally.
