Chinese surnames are used by Han Chinese and Sinicized ethnic groups in Mainland China, Hong Kong, Macau, Malaysia, Taiwan, Korea, Singapore, Vietnam and among overseas Chinese communities. In ancient times two types of surnames existed, namely xing (Chinese: å§; pinyin: xÃ¬ng) or lineage names, and shi (Chinese: æ°; pinyin: shÃ¬) or clan names.
An ice sheet is a large permanent layer of ice covering a continental shelf, defined as having an extent greater than 50,000 km2 (19,305 mi2). An ice sheet is larger than a glacier or ice shelf.
The ice playing surface is called a 'sheet' and is within a 'curling rink'. The 'sheet' is 138 feet long by approximately 14 feet wide. The main features of the sheet are the 'House', the 'Hack', the 'Hog Line' and the 'Tee Line'. The 'Hack' is where one delivers or throws the stone.
