“…17 During the late Han period, a comprehensive list of titles and means of address for various family members was detailed in the document Shiming [An Explanation of Names]. 18 These ideas would prove most prevalent in rural and coastal regions of China, where farming, fishing, and other forms of agriculture sustained the livelihoods of families. In rural areas, a family's survival depended on the might and muscle of male family members.…”

Shim-pua marriage, also known as tongyangxi, is a traditional Chinese practice where a poorer family’s infant daughter is sold into a wealthier family in exchange for a dowry. The daughter would grow up in the new family, often subjected to difficult chores and maidwork. As the girl matured, she would then be forcefully married to one of the family’s sons. Shim-pua marriage persisted through multiple phases of cultural, social, and political change. But this persistence is indicative of a larger social phenomena. The recurrence of the practice results from the failure of top-down intervention to change underlying social norms. Additionally, Shim-pua marriage is closely connected to modern issues such as human trafficking. This paper provides an in-depth view and analysis of historical revolutions, government action, and people’s response with respect to Shim-pua marriage. It explores the underlying causes of the practice’s persistence, and the socio-economic conditions that fueled it.

This paper presents a simple quasi-common path point diffraction interferometer (PDI) that allows fringe contrast and fringe spatial frequency to be adjusted conveniently. The novel aspect of this PDI is the use of a polarizer with pinhole as the PDI mask-and then, with a compact circular optical setup, reference and measurement waves are obtained. Furthermore, a linear tilting modulation is added into two interfering waves and adjusted easily by tilting the polarizing beam splitter-and hence the Fourier transform method can be perfectly applied to extract the wavefront phase from the captured fringe pattern, with the highest fringe contrast and suitable carrier frequency. Detailed theoretical analysis and experimental results are presented.
