In addition to taking pictures with Santa Claus in Santa Claus Village, the second thing is to step on the back line and prove that you have actually been to this place. The Tropic of Cancer is actually a circle. It often snows in winter and may not be seen on the ground. Therefore, several large pillars have been set up. There will also be this line indoors, so check it out and step on it. The third thing is to go to the Santa Post Office to send yourself a postcard. Santa's post office has two mailboxes, one is slow delivery, one is express delivery, if you want to give yourself after many years, you can choose slow delivery. The big lion seems to never do anything to post postcards to himself ten years later, so I chose express, and, and the results have not been received yet.
