Well, I started to learn Chinese two months ago and literally I have consumed tons of information about China on YouTube and some blogs on internet and also chatting with some Chinese friends that I made before to took the decision to learn Chinese.
There are so many interesting aspects about China that is tough choose just one. Therefore I will show the most recent aspect that caught my attention. Nowdays in there two terms that are very fashionable in internet.
小哥哥 (little brother) it is use to talk about a guy with the following features: cool, young and handsome.
The next one is 小姐姐 (little sister) basically is the same case the latter term but in a female version, a pretty sweetheart female.
So now when I meet a Chinese girl always introduce myself as 小哥哥 after that start to called my new female friends as 小姐姐 is an easy way to break the ice with people from China.
I hope this has been interesting or useful for you.
