Is Shandong Long Mai in Qingdao or Yantai?

In Yantai. That should be the mountain around the mountain road tunnel, because it is said that it is Long Mai. There was no tunnel at that time. It was dug directly. Then Yantai's economy was depressed. After the then mayor called Mr. Feng Shui to explain the situation, Mr. Feng Shui said that Long Mai was cut off. Then the mayor took Mr. Feng Shui around Yantai and went to the tunnel around the mountain road to say that it was cut by Long Mai. What should the then mayor say? Can you connect them? Mr. Feng Shui said yes, and then there was a tunnel around the mountain road. I've only heard of it, but I asked the old man that it was really dug around the mountain road before it was connected to the tunnel.
