Two jokes are currently circulating in Chinese cyberspace which take on current events:
The first one refers to recent tensions over the East China Sea.
[Diaoyu Islands belong to which country?] Answer: Bring a laptop computer there. If you can open Twitter, they belong to Japan. If you can’t open Twitter, they belong to China!
The second one references a recent order that homes, temples and schools in Tibet must display portraits of China’s leaders.
Cadres went from house to house to ask: Have you hung all the leaders [portraits]? They all answer: Hung, we hung them all!*
* The word 挂 (gua) literally means to hang, but is also online slang for “dead.” So the double-entendre is: “The leaders are all dead!”
