Zhen Wu of Zhaoyuan County mentioned in Strange Tales from a Lonely Studio, where is it now?

In Pu Songling's Strange Tales from a Lonely Studio, there are many stories involving Jiaodong area. For example, Sun nine niang reflected in the Seven Anti-Japanese Incident, Water Spray by Song Wan, a celebrity in Laiyang in the early Qing Dynasty, and so on. Although Pu Songling is not from Jiaodong, his birthplace is Zichuan, which is not too far from Jiaodong. It makes sense that what he saw and heard was related to Jiaodong. In the story Wang Liulang, Pu Songling mentioned a place name in Jiaodong, Zhen Wu, Zhaoyuan County. "Wang Liulang" is the first long story in the first volume of Strange Tales from a Lonely Studio, and I believe all friends who have read this book should have an impression. Relatively speaking, although this story is haunted, it is not scary, but rather "human", and its central idea of repaying kindness is also very willing to be accepted by readers. The general outline of this story is that a man surnamed Xu in Zichuan takes fishing as his profession. He likes to get off the net at night and drink while working. When drinking, he will sprinkle some on the ground as a sacrifice and leave a message: "Ghost drowned in the river, have a drink." "As a result, every time I go fishing, others get very little. Only this man named Xu comes home with a full load. Only later did I know the reason. It turns out that there really is a drowning ghost named Wang Liulang in this river. Wang Liulang drowned because of drunkenness. Every time the people named Xu spilled wine on the river ghost, Wang Liulang drank it. In order to repay this kindness, Wang Liulang always catches fish for Xu upstream to help him get a bumper harvest. Although Wang Liulang was already a ghost at that time, he had a heart to repay his kindness, and the Xu family also accompanied him for some time. Therefore, after he exposed his identity, the Xu family was not afraid, but as always became friends who never looked back. Then one day, Wang Liulang suddenly said goodbye to Xu, saying that when he was a ghost in the river, someone would replace him. Unexpectedly, the next day, a woman with a child fell into the water, and Wang Liulang was pitied and rescued the woman ashore. Without body double, Wang Liulang continued to be a ghost in the river, and people surnamed Xu still got along with him. After a while, Wang Liulang said goodbye to Xu again. This time, it was not replaced by someone, but because his last move to save people touched the sky. Being deified, it was transferred to the land god of Zhen Wu, Zhaoyuan County. After getting along for a long time, they are reluctant to go, and they meet again in Zhaoyuan. After Xu's family came home, they set off immediately. He "made a costume and walked hundreds of miles east". When he came to Zhaoyuan County, he found a place called Zhen Wu. When I arrived in Zhen Wu, I didn't see Wang Liulang, but I was warmly received by the local people. It turned out that the land god gave the local people a dream that a friend named Xu would come from Zichuan and let them have a good reception. Deeply moved, Xu burned paper and money for sacrifice, and met Wang Liulang in his dream at night. The story ends in a happy way. It is mentioned in the story that Wang Liulang is a land god and Zhen Wu of Zhaoyuan County. Where is this Zhen Wu now? Looking up the map of Zhaoyuan, there is no place called Wu Town in Zhaoyuan at present, and the next best thing is that there is no place with Wu characters. Only a few villages have the word "Wu", that is, the Northern Wu Party and the Southern Wu Party in the suburbs, and the Daxia Wu and Xixia Wu in Biguo Town. Presumably because Pu Songling is a foreigner, the place name of Zhaoyuan is abbreviated, and Zhen Wu may mean "Wu" ("pier"). So, which of these villages with pier characters in Zhaoyuan may be Pu Songling's Zhen Wu? Inquiring about Zhaoyuan's place names can basically rule out the possibility of Daxiawu and Xixia dock. According to records, the original name of Daxiawu didn't have the word wharf, but it was changed to Wu Xia in the light years of the Qing Dynasty, and so was Daxiawu. In contrast, it is more likely that there is no party in the north and the south. According to Zhaoyuan's place names, the five northern and southern parties are about 6 miles southeast of the county seat, near the Donghe River in Zhao Cheng. Due to the alluvial river, a dock pond was formed here in history, which was named after it when the village was built in the early Yuan Dynasty. In the early Ming Dynasty, Shanxi Sophora japonica immigrated here, changed the name of the village to Wutang Town, and later became a pier party. The names Wutang Town and Wuzhen are logically similar. Under the communication and traffic conditions at that time, people surnamed Xu should go directly to the county seat and ask again when they get there. According to the original records, people surnamed Xu found Zhen Wu soon after they arrived in Zhaoyuan, proving that Zhen Wu is not far from the county seat. Taken together, Dangcun in Nanbeiwu, Zhaoyuan City is probably Wuzhen, Zhaoyuan County described by Pu Songling. I wonder if people there have heard such a legend mentioned by their ancestors?
