Why didn't the Ming Dynasty send women to Mongolia to buy peace like the Qing Dynasty?

The Qing dynasty did not completely give women to Mongols. For example, sourdrang queen is a Mongolian. I'm afraid sometimes Mongolia sent women to the Qing Dynasty.

However, the policies of the Ming Dynasty were really true. Because the Ming Dynasty was founded by defeating Mongolia, it always regarded Mongolia as its enemy. Basically, the whole dynasty is at war with Mongolia, and it is difficult to defeat Mongolia. Then the Qing Dynasty rose again.

The policy of the Ming Dynasty was to be absolutely tough with foreign countries. He didn't cede territory to the outside world like the Qing Dynasty, didn't compensate with money like the Song Dynasty, and didn't kiss Han and Tang Dynasties. Whether his monarch is fatuous or not, at least he did it. When the king dies, the son of heaven protects the country. In the change of the civil fort, Ming Di was captured, not signing an alliance at the gate, and another emperor continued to fight.

Perhaps the Ming Dynasty was not the strongest dynasty, but it was definitely the bravest dynasty abroad.
