Should i bring Autumn/Fall clothes or Winter Clothes for Beijing next week?

Right now China is becoming drastically colder by the day, with snowfall in several cities already, winter clothes.

You are vastly underestimating the quality of tyres in China - if you imagine they will skid and hit a tree, it won't, period. This isn't the first, nor the last winter in China, I think they know what they are doing, especially since they experience the same cold every year.

There are two routes up Badaling (the most popular section of the Great Wall, outside Beijing), one is a gondola service carrying you to the top tower, or by walking, where you get to experience the full length of the climb and its associated sceneries. I suggest the latter, you get the full experience and without the annoying tourists ruining the view.

However, climbing the Great Wall is slightly risky at best, even in temperate climate, with high slopes and stairs (the wall is essentially constructed on the ridge of mountains), if you're not the sporty type it's going to be tiring, do take extra care.

The temperature of Beijing now is very cold, you should bring down jacket and cotton shoes with you. The weather of Beijing is sunny next week. If it snows, the buses and taxi are also the safe. Don't worry! If you have no ideas about travel to Beijing, you can jion a Beijing travel agency. The travel guide will give you more helps.

Welcome to Beijing!

Of course winter clothes.

Those Japanese were died because they have no brains, only fools would start to climb wild Great Walls on MIDNIGHT without noticing the weather forecast, or else they have stupid confidence on their strong body even though they are already 60+ years old.
