I had a most gratifying experience today when I saw a response on Twitter and understood what the meme was saying.
The words
你 知道 我 要 说 什么
nǐ zhīdào wǒ yào shuō shénme
mean "You know what I want to say" (literally "You know I want say what")
The deliberately neutral expression on the man's face says it all. He has an opinion, but isn't saying anything.
I was so pleased that I was able to read and understand every character in the meme, and best of all, understand what the meme meant.
Understanding this meme from pop culture is another small milestone in my journey to gain better insights into Chinese society.
