Excuse me, which is worth visiting, Luxun Park or Zhongshan Park? Is it necessary to go to Xiaoyu Mountain and Signal Mountain?
I suggest going to Xiaoyu Mountain, but it doesn't matter whether Signal Mountain goes or not. But to tell you a message, China's sea level benchmark is on Signal Mountain, which I really haven't seen. I just saw the photo in the newspaper. It seems to be a small house surrounded by several locks, and there is an instrument in it, which I have never seen before. The commemorative value is greater than the visiting value, hehe.
One more thing: you can see most of Qingdao's urban areas on Signal Mountain; Xiaoyu Mountain is not too high, so it is good to see the scenery of Qianhai. If you really want to see the whole picture of Qingdao, I suggest you stick to the TV tower on Forest Hill. It's best to watch it in a place with good weather. Tickets are around 15 yuan.
