According to research conducted by Wu Shwu-chung, an associate professor in the Institute of Public Health at National Taiwan University, one-third of the island's elderly are ca red for by a spouse. Another third are looked after by a daughter-in-law. This is clearly the root of the problems that exist between mothers-and daughters-in-law.
根據台大公共衛生研究所副教授吳淑瓊的研究，三分之一的老人由老伴照顧，另外三分之一的老人由媳婦照顧，這也正是婆媳問題的根源。
