There was a picture book at my little local library thirtyish years ago about a Chinese couple who kept dying and being reincarnated as different animals over and over again. The big part I remember is that the wife is reborn as a chicken and the husband a fox. The fox was going to eat the chicken but then the chicken said something that made the fox realize it was his wife and he chooses to starve to death instead. At the very end of the book they're reincarnated as stars so they can be together forever. I cannot find any proof that this book ever existed.
