Take an EMU with your parents and go to Nanjing to play. My parents play Zhongshan Mausoleum and Ming Xiaoling Mausoleum. I took my daughter to play in the ocean world. If my daughter is less than one metre two, I'll just buy a ticket. It's a good deal. There are four layers in the ocean world. The first layer is the most beautiful jellyfish. The undersea tunnel is also very beautiful. The emperor penguin on the third floor is very big and lovely. It walks shakily and swims flexibly, so that its daughter refuses to stand. There are polar bears. They weigh a kilo. The servant always throws something to eat. He walks or swims, or rubs himself against the glass. It's amazing and frightening to see this huge thing at such a close distance. Ha-ha. We stayed in it for more than two hours, because we had to go somewhere else to play before we reluctantly left.
