Because Dad works in water conservancy, it's meaningful to see the biggest water project with him. Unfortunately, the children are too young to understand. There are three scenic spots in the dam, all of which are conveniently transported by bus. Battery cars in scenic spots can be used without sitting. First, they are too close. It takes two or three minutes from the lock platform to the 185 platform. Second, there are many people in the queue, so the time of queuing can already take a walk around the river closure park. With a long-sighted mind, the dam is still worth visiting.
