 Passage 2:Kazusa was originally part of a larger territory known as , which was divided into "upper" and “lower” portions (i.e. Kazusa and Shimōsa) during the reign of Emperor Kōtoku (645–654). It was well-known to the Imperial Court in Nara -period Japan for its fertile lands, and is mentioned in Nara period records as having supplied hemp to the Court. Kazusa was divided into 15 counties, of which the four counties comprising the district of Awa were separated in 718 into a separate province. The exact location of the capital of Kazusa is not precisely known, but is believed to have been somewhere within the borders of the modern city of Ichihara, Chiba. The ruins of the kokubun-ji, or provincial temple, of Kazusa has been located in the Sōza district of Ichihara. The kokubun-ji was first excavated in 1949, and is on a plateau above the Yōrō River in close proximity to Tokyo Bay. The site is protected as a Designated Historic Site of Japan. However, the Ichinomiya of Kazusa Province is the Tamasaki Shrine in what is now the town of Ichinomiya, Chiba, on the opposite coast of the province.
 Passage 3:A native of Hsinchu County, Wang was born in 1954. He began swimming in the Touqian River at a young age, and in college, started swimming the ocean. Wang's first publicized attempt at long-distance swimming in 1985 was funded by the actors' guild of which Wang held membership. He swam from Donggang, Pingtung, to Liuqiu Island in approximately six hours. Subsequently, aged 31, he chose to retire from acting and modeling to concentrate on swimming. In August 1986, Wang swam the Strait of Gibraltar. From 1988 to 1998, Wang traversed one body of water per year, including the English Channel (1988), Bosporus (1989), the channels of the Hawaiian Islands around Maui (1990), the Strait of Juan de Fuca (1993), the Tsugaru Strait (1994), Cleveland Bay (1996), and the Strait of Sicily (1998). He had originally planned to swim the Taiwan Strait in 1998, but did not do so, as it was too soon after the Third Taiwan Strait Crisis. Wang was consulted about plans to swim the Taiwan Strait in 2001, and scheduled his own attempt throughout 2007, after receiving help from Chi Cheng. The 2007 attempt was unsuccessful, and Wang made plans for the strait in January 2008, though this last attempt received no further media coverage.
