Sail

A sail is a catchment device designed to receive and redirect a force upon a generous surface area. Traditionally, the surface was engineered of woven fabric and supported by a mast, whose purpose is to propel a sailing vessel. Sails may be configured in many ways to include traditionally understood maritime purposes, as well as land vehicles and solar collection purposes. The rich encyclopedic history of maritime sails suggests alternative uses of the technology well documented.

History of sails

Archaeological studies of the Cucuteni-Trypillian culture ceramics show use of sailing boats from the sixth millennium onwards. Excavations of the Ubaid period (c. 6000 -4300 BC) in Mesopotamia provides direct evidence of sailing boats. Sails from ancient Egypt are depicted around 3200 BCE, where reed boats sailed upstream against the River Nile's current. Ancient Sumerians used square rigged sailing boats at about the same time, and it is believed they established sea trading routes as far away as the Indus valley. The proto-Austronesian words for sail, lay(r), and other rigging parts date to about 3000 BCE when this group began their Pacific expansion.Greeks and Phoenicians began trading by ship by around 1,200 BCE.

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.

South China

South China (simplified Chinese: 华南; traditional Chinese: 華南; pinyin: huá nán) is a geographical and cultural region that covers the southernmost part of China. Its precise meaning varies with context.

Definitions

In the broadest sense, Southern China can denote the entire portion of the country south of the line demarcated by the Qin Mountains and Huai River. Between 1945 and 1949, the Republic of China defined Guizhou, Yunnan, Guangdong, Guangxi, Hainan, Fujian and Taiwan as the "Seven Provinces of South China" (simplified Chinese: 华南七省; traditional Chinese: 華南七省; pinyin: huá nán qī shěng). The term can also be used to denote the Lingnan region; but today, the phrase is generally used to refer only to Guangdong, Guangxi, Hainan, Hong Kong and Macau (historically also known as Liangguang). Defined as such, South China is also contained within South Central China.
