The facebook post mentioned that 意見 (いけん) and アドバイス is commonly misused by Japanese speakers whose native language is Mandarin.
According to the OP, アドバイス is used when a superior speaks to an inferior, closer to 意見 (strong opinion) in Mandarin.
On the other hand, 意見 in Japanese does not have a negative meaning, but is more of a suggestion, being closer to 建議 (advice / suggestion) in Mandarin.
I would like to hear different people's opinions and experiences on the Japanese part.
