What should a southerner pay attention to when traveling to Harbin for the first time? Is there a travel guide?

Ice and Snow World 1. It is recommended to buy a VIP ticket for over 800, which is free of queuing all the way. We thought it was unnecessary at the time, it was okay to queue up, so we bought one for over 300. We really queued for 6 hours on the big slide, cold and tired, it was really uncomfortable. And in the end, there was no time to go to the Ferris wheel (because there were also many people queuing up) which means we played the slide once for over 300. 2. The temperature in Harbin was okay during the days we were there, and it was enough to wear a base layer + thermal underwear + fleece jacket + storm jacket and pants + earmuffs + gloves. But if you want to queue in the Ice and Snow World, you still need to bring a down jacket. We felt stupid when we went out with the down jacket, but we found it was wise at night. 3. It's hard to take pictures in the Ice and Snow World, the scenery is too big, and when the lights are on, it's basically backlit shooting. 4. If you want to take pictures, try to buy larger clothes, because with hats and various clothes stacked, people will swell a size, and if you buy too small, you will look fat. 5. The heating insoles work. 6. If you want to rent a snow ring in the Ice and Snow World, rent it after playing the big slide and Ferris wheel, because you can't bring it in, we can only put it outside, and it was indeed lost. 7. Girls queue up for the toilet until they doubt life, it is said that some people deliberately stay inside for half an hour because it is too cold outside. 8. If you want to go to the toilet while queuing for the big slide, it is recommended to find a staff member, if you go out by yourself, the people behind may not let you in. 9. If you plan to come to Mohe, the Christmas Village is a substitute, the ticket is low, there are also small slides and various ice sculptures, and Santa Claus, and there are few people, you can play to your heart's content. It's just that there is no Ferris wheel.
