Is it two townships or one township to send firewood to serve the palace?

Two towns and villages. When Wang Changling, a poet of the Tang Dynasty, was sent to Longbiao, his friend Chai wanted to go to Wugang from Longbiao. The poet wrote this poem to see him off. In the poem, "The flowing water connects Wugang, so you won't feel hurt when you send your monarch away" means that the water color of Yuanjiang River connects Dongting Lake, so you won't feel hurt when you send your monarch away. Among them, "water and waves are connected" means that water and waves are connected. Therefore, the "two townships" here refer to the two places where the author and his friends Chai Shi and Yu live apart, namely Longbiao and Wugang.
