Excuse me, what's the temperature here on the Great Wall of Arrow Buckle during the May Day holiday? What clothes are suitable for camping? And prepare for a two-day trip. What is the best route?

There is no through train for the arrow buckle, so you can only drive or take a taxi by yourself. The temperature on the Great Wall is still very low, so you need to wear windproof, warm and breathable clothes. The temperature in Beijing has been dropping recently, so you'd better check the short-term weather forecast before you go. Also, you can't climb the Wild Great Wall casually now, or you will be fined.
