Sail Before the Wind (aka May Luck Be With You)

A penny-pinching jewellery shop owner promises his entire fortune to the son who first bears him a grandson. What ensues is a battle of wits among his three sons and daughters-in-law. Upon knowing that the youngest son's wife is pregnant, the other two wives put on an act and enter the fray with their faked foetuses. Their plot soon reaches due date though, and family tension soars to all-time high. To help restore peace, the youngest son volunteers to give his first two new-borns to the disgruntled brothers. As it happens, his wife gives birth to triplets, but only the last one is a boy. All's well that ends well - the selfless heir chooses to divide his wealth equally with his siblings
