There are too many people going on May Day. It takes at least half an hour to watch the sea lion show, otherwise there is no place to stand cone when it arrives. At that time, I watched the broadcast on the mobile phone of the front row audience. Going to the undersea tunnel requires fewer people to go in, otherwise it will be blocked in the middle of the road and breathing is difficult. In short, when there are few people, it is still possible to watch.
