In 1985, 25-year-old Wang Tiezhu came back from the dead with four "big mountains" on his shoulders - four half-sons. Three entangled pasts left him entangled in two unbroken feelings. Ex-wife No. 1 Looked forward to him, hoping that he would come back. Ex-wife No. 2 Looked at her with a cold face, but the same obsession was hidden in her eyes. The burden of raising a family was as heavy as a mountain, and thoughts of escaping grew wildly, but looking at the concerns of two women and four immature children, he couldn't take the step to leave after all.
