Yes, his own coffers are more important than anything else, just because Emperor Chongzhen was stingy by nature.

Emperor Chongzhen was the last emperor of the Ming Dynasty. Before he became the emperor of the Ming Dynasty, this country was ruled by eunuchs. As soon as he ascended the throne, he began to purge all eunuchs. The first winner was Wei Zhongxian, and then he began to rule with great strength. Emperor Chongzhen is famous for his diligence and housekeeping. No matter what happened, he didn't take any more flowers, so he had to make do. Extravagance is not his character.

How frugal and stingy was Emperor Chongzhen? He likes writing and edifies his sentiments. After the front of the rice paper he used is full, it should be full on the back after a while. If you have to buy things in the palace, you must bargain with the vendor. If you don't bargain, I'll kill your head in Chongzhen. Singing and dancing are not allowed on festive days. In a word.

In fact, in addition to his personality, there is another reason that the treasury of the Ming Dynasty is really poor. Every year, the money handed in from below is so small that it is impossible for him to expand. When Li Zicheng, the king of Zhuang, led the army and wanted to spend some money to move reinforcements, the money was confiscated. The state treasury has no money, but the Chongzhen small treasury has it. He just didn't take it out, saying that he wanted Manchu civil servants to pay for it.

I estimate that if Chongzhen had been willing to take money out at that time, he would not have been beaten so badly, and he might have been able to toss around for three to five years. But what is certain is that Chongzhen really wanted to do a good job in the Ming Dynasty, revive the national prestige, and do everything to make his ancestors appear in the spirit of heaven, but the Ming Dynasty is hopeless.
