Einstein and Einstein (Chinese: 狗十三; pinyin: Gǒu shísān; lit. 'Dog 13') is a 2013 Chinese film directed by Cao Baoping.

It is about a 13-year-old girl named Li Wan (李玩), played by Zhang Xueying (simplified Chinese: 张雪迎; traditional Chinese: 張雪迎), who struggles with her parents after her dog runs away.

It was first played in October 2013 at the Youth Generation International Film Forum, and it was first played in theaters in China in 2018.^{[citation needed]}

Elizabeth Kerr of The Hollywood Reporter wrote that the film has "a happy ending that suggests the modernization of China is an iterative process that will trickle down to the Li Wans of the world — eventually."^[1]
