What do you mean by northern lymph node tuberculosis?

This is what southerners call people who speak northern accents.

The word "northern scrofula" originated in the Southern Song Dynasty, when there was a war in the north. In Song Dynasty, the royal family moved from Tokyo (now Kaifeng, Henan) to Lin 'an (now Hangzhou, Zhejiang), and the economic center of China moved to the south of Huaihe River. Many northerners immigrated to the south.

This word is used by the local people born and raised in the south to describe the northerners who moved south with the royal family in the Song Dynasty, which is quite ironic. This word corresponds to "Nanmanzi", which is a contemptuous word for locals or foreigners with foreign accents.

In modern times, some people use this word to refer to people in areas farther north than their hometown.
