 Sichuan (help·info) (Chinese: 四川, known formerly in the West by its postal map spellings of Szechwan or Szechuan) is a province in Southwest China with its capital in Chengdu. The current name of the province, "四川", is an abbreviation of "四川路" (Sì Chuānlù), or "Four circuits of rivers", which is itself abbreviated from "川峡四路" (Chuānxiá Sìlù), or "Four circuits of rivers and gorges", named after the division of the existing circuit into four during the Northern Song Dynasty.

The province and its vicinity were the cradle of unique local civilizations, which can be dated back to at least the fifteenth century BC (coinciding with the later years of the Shang Dynasty). Beginning from the ninth century BC, Shu (today Chengdu) and Ba (today Chongqing City) emerged as cultural and administrative centers where two rival kingdoms were established.

Shu's existence was unknown until an archaeological discovery in 1986 at a small village named Sanxingdui (三星堆) in Guanghan County. It is believed to be an ancient city of the Shu Kingdom, where excavations have yielded invaluable archaeological information.

Gordon James Ramsay, OBE (born 8 November 1966) is a British chef, television personality and restaurateur. He has been awarded 13 Michelin stars in total and currently holds 12.

Ramsay is known for presenting TV programmes about competitive cookery and food, such as the British series Hell's Kitchen, The F Word, Ramsay's Best Restaurant, and Ramsay's Kitchen Nightmares, along with the American versions of Hell's Kitchen, Kitchen Nightmares, and MasterChef.

Gordon Ramsay was born in Johnstone, Renfrewshire, Scotland, and raised in Stratford-upon-Avon, Warwickshire, England from the age of 5. Ramsay is the second of four children; he has an older sister, Diane, a younger brother, Ronnie, and a younger sister, Yvonne. Ramsay's father Gordon (died 1997) was, at various times, a swimming pool manager, a welder, and a shopkeeper; his mother, Helen Cosgrove, and Yvonne have been nurses. Ramsay has described his early life as "hopelessly itinerant", as his family moved constantly due to the aspirations and failures of his father, who was violent. In 1976, they finally settled in Stratford-upon-Avon where he grew up in the Bishopton area of the town. In past public interviews, Ramsay has declined to describe his father as an alcoholic; however, his autobiography, Humble Pie, describes his early life as being marked by abuse and neglect from this "hard-drinking womaniser". At the age of 16, Ramsay moved out of the family house into a flat in Banbury.

Jin Li (Chinese: 金力; pinyin: Jin Li) is a Chinese geneticist. Jin is a professor at the National Human Genome Center in Shanghai as well as at the Institute of Genetics of Fudan University. Jin is the principal investigator of East Asian populations for the Genographic Project which collects DNA samples to map historical human migration patterns around the world.

He is a leading proponent of the model of recent African origin of modern humans. His research presented evidence that the majority of the gene pools in China originated from Africa. His team analyzed the Y chromosomes of males around China and compared this group with those of Southeast Asians and Africans. Results of the analysis suggested that Southeast Asia was the first destination of the migration from Africa to Asia which began approximately 60,000 years ago; from there, migrants moved into Southern China, then crossing the Yangtze River to Northern China. He "could not find any evidence that is consistent with the hypothesis of independent origin in China" in the 1998 study which used genetic markers called microsatellites to compare Chinese populations. He stated that while his research does not necessarily rule out independent origin, the burden of proof has been shifted to those who believe in independent origin. The findings contrast with the hypothesis that the Peking Man was the ancestor of Chinese people.
