HSK

HSK stands for Hanyu Shuiping Kaoshi, which is a test to assess your Chinese proficiency. I took HSK level 4 (Upper-imtermidiate) a month ago and today I found out that I passed the test!! I've been studying Chinese for almost 3 years and this is the day that I have an official certificate to prove my Chinese proficiency for the first time. 

The Chinese characters, 合格, in my blip means pass in Japanese.
