Another thing I really like about china is the amount of taxis.
还有一点让我比较喜欢中国的就是，这里有很多出租车。
Well, I'd have to say it's the food, and the availability of food. It's everywhere!
嗯，我必须说的一点，就是这里的食物随时随地都可以容易的得到！
One of the things I find amazing about WeChat pay and Ali pay is how easy it is for everyone to use, and how widespread it is.
我觉得中国最让我惊讶的一点，就是微信支付和支付宝支付的广泛性，基本上大家都在用！
These shouldn't be confused with "Bar codes" which can be found on things we buy from stores.
我们不要把二维码和条形码弄混，条形码是在超市买东西的时候扫的。
