The great-grandmother is Feng Guixiang, the "nail house" in the underworld. In order to examine whether contemporary society is worthy of reincarnation, she embarks on a hilarious journey through time. She uses her century-old wisdom to interpret her grandchildren's 996, her son's mid-life crisis, and her grandchildren's marriage puzzle. She searches for the answer to love in the maze of mobile phones, mortgages, and chickens. This is a warm watch that spans centuries, a love letter written by an old soul to tired modern people - when the whole world urges you to run fast, someone will always ask you if you are tired.
