三色猫 (Tortoishell cat or calico cat / sansemao, literally: “tri-color cat”)
Why it is blocked: Actually, a search for any colored cat, so long as it uses the term “色貓” is blocked. This is a reference to Deng’s famed 1961 proverb in favor of market reforms: “It doesn’t matter if the cat is black or white, so long as it catches mice it’s good” (不管黑猫白猫能捉到老鼠的就是好猫, or something similar: searching for the term shows several variations). Perhaps the term was previously used to mock the current system of “socialism with Chinese characteristics.” Regardless, it is now apparently a sensitive topic (though you can freely perform a search for Deng’s proverb itself).
