Today is young Chinese Valentine’s Day because the pronunciation of the date “520” is really like “I love you” in mandarin. Then, some youngers make propose, some make wedding ceremony, some send rose flowers to lover, some transfer “red package红包“ by the number ￥520 etc. I just made chatting on video with my wife in Wechat, but our sweetheart daughter received rose flowers from somebody. This phenomenon is a kind of Chinese culture like use bat as “lucky” due to the pronunciation are quite similar.
