Another thing I really like about china is the amount of taxis.
還有一點讓我比較喜歡中國的就是，這里有很多出租車。
Well, I'd have to say it's the food, and the availability of food. It's everywhere!
嗯，我必須說的一點，就是這里的食物隨時隨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.
我覺得中國最讓我驚訝的一點，就是微信支付和支付寶支付的廣泛性，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.
我們不要把二維碼和條形碼弄混，條形碼是在超市買東西的時候掃的。
