What is the origin of Jiangxi abbreviation?

As the mother river of Jiangxi, Ganjiang River starts from Ganzhou in southwest Jiangxi, runs through the whole province of Jiangxi from south to north and flows into Poyang Lake, so it is called Jiangxi Province for short. ?

I think few people can use the word "Jiangxi" except Jiangxi people. "Jiangxi" is unique to Jiangxi. There are two interpretations of "Gan" on page 446 of Modern Chinese Dictionary (5th edition) published by the Commercial Press: ① Ganjiang, whose name is water, is in Jiangxi. ② Jiangxi is another name. It can be seen that the word "Jiangxi" is inseparable from Jiangxi. Anywhere, as long as we talk about "Jiangxi", we must refer to Jiangxi. Jiangxi is Jiangxi, and Jiangxi is Jiangxi. ?

What is the pronunciation source of the word "gan"?

The controversy about pronunciation is similar to his font. Based on Zhang Zhang's two integration methods, one is to read the clock with Zhang Zhi's voice and Gong Zhi's rhyme, and the other is to read the clock with Gong Zhi's voice and Zhang Zhi's rhyme.

Because Gan characters are arranged around the natural layout of the two rivers, people who support Gongjiang think that Zhang characters come first and are very dissatisfied. They asked for the pronunciation of Gong, so they got the pronunciation of Gang, but the pronunciation of this combination is homophonic with the word "bar".

Ganzhou people pay attention to feng shui and believe in this reputation. In order to avoid this bad homophonic sound, they changed the pronunciation of Gang to Gan, which is not only homophonic with the word Gan, but also reflects the fine style of hard work of Ganzhou people. And because Ganzhou people always like to make nasal sounds before and after, they can't detect any difference. ?
