Tàikāng
Taikang is an old county town southeast of Kaifeng, formerly known as Yangxia. Its earthen walls were built in the Yuan and enlarged under the Ming, while a Confucian temple was founded in 1426. In 1636 the walls were faced with brick, but six years later Li Zicheng's army took the town after a siege. The walls and temple were destroyed in the fighting, and both were rebuilt in the early Qing.
