The flood cave tree of Shanxi

My last name is Hong Kong, which is a relatively small name, but common in my hometown. A year ago, a man came to us looking for his ancestors. He said he grew up in Hebei and never had the same name around him since he was a kid. He asked Grandpa where he came from, and he said your little toenails split in half, which means you're a Hung Hole Man! Our ancestors moved here in a great migration, "to ask my ancestors where they came from, the flood cave tree." Grandpa says you have to go back when you grow up. And from that time he told himself that he would grow up and go to the mountains to find his fathers. When he grew up, he gradually forgot to do so until he retired, and when he was in his mid-50s, he travelled to Shanxi, finally fulfilling his childhood dream. He went to the flood hole in Shanxi and found the legendary tree, but found that there was no one with his name. Under the tree, he turned and looked. He learned from the mouth of the local elders that hundreds of kilometres from the flood hole there was a village named after the line! He went to that village and found that there was no one with the same family name, and he went around several times, and he learned that another village was where he was looking. He wanted to give up, but think about his childhood dream, and he decided to try. He found our village. He asked the village's elders, where's the expert? The old man asks, "Who are you looking for?" He knows he found it! He cried, his childhood wish finally came true, and his dreams were fulfilled by generations! His arrival has brought together the already scattered men of the past, who will continue to worship their common ancestors from the following year
