Chinese family names are patrilineal, passed from father to children. (In cases of adoption, the adoptee usually also takes the same surname.) Women do not normally change their surnames upon marriage, except in places with more Western influences such as Hong Kong.
Ice shelf. An ice shelf is a thick floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland and Canada. The boundary between the floating ice shelf and the grounded ice that feeds it is called the grounding line.
Ice shelf collapse. Several of the ice shelves around Antarctica have recently collapsed dramatically, rather than retreating in a slow and steady manner. Larsen A collapsed in 1995[6], and Larsen B Ice Shelf famously collapsed in 2002. It has shrunk from 12,000 km 2 in 1963 to 2400 km 2 in 2010[4]. During February 2002, 3250 km 2 were lost through iceberg calving and fragmentation.
