In the zoo you can see "Wo Cao Ni Ma", on Taobao you can buy the doll "Wo Cao Ni Ma", and even in the relevant entries of Baidu you can also find an explanation for "Wo Cao Ni Ma". If you really think there is such a horse, you're dead wrong. It's just a parody by netizens of a Chinese swear word. However, a PhD in Shanghai was misled, saying in a media interview that "the word Wo Cao Ni Ma comes from the Stratagems of the Warring States", causing a stir online.
