Anping Bridge consists of 331 spans of granite beams resting on top of stone piers, the largest beam weighing 25 tons. The width of the bridge varies from . It originally had five pavilions where travelers could rest; however, only one pavilion (Shuixin Pavilion) still exists. Construction of the bridge started in 1138 during the Southern Song dynasty and lasted until 1151. It was originally 811 "zhang" [] long and 1.6 "zhang" [] wide, with 362 spans. Upon completion, it was the longest bridge in China until 1905, inspiring the local description, "No bridge in the world is as long as this one" (). There have been six major repairs since its opening, and the bridge is now shorter due to silting of the estuary. The estuary of the Shijing River has mostly silted up in this area, and the remaining river channel under the bridge is fairly narrow. Consequently, the bridge now mostly crosses what amounts to a sequence of lakes or ponds, separated by wetlands. A modern public highway crosses the Shijing River a few hundred meters south (downstream) of the historical Anping Bridge over a fairly short bridge. The areas around the bridge are being developed into parks. Rosenberg's fruit-eating bat  Rosenberg's fruit-eating bat ("Dermanura rosenbergi", often misspelled "rosenbergii") is a species of bat in the family Phyllostomidae. It is found in humid tropical forests in the El Chocó region on the coast of western Colombia and northwestern Ecuador at altitudes below 500 m. Until recently it was included within "D. glauca", a canopy frugivore that also eats insects. It was elevated to full species status in 2009. The specific name is in honor of collector W. F. H. Rosenberg. The species is regarded as common, but is likely threatened by the deforestation of its habitat. Nias Expedition  The Nias Expedition was a punitive expedition of the Royal Netherlands East Indies Army to Nias at the end of 1855, which, with intervals, lasted until 1864. Nias (Nias Island) was an almost isolated island. The distance of Nias Island from the mainland Sumatera made Nias Island become almost isolated from Srivijaya and Majapahit. But, Nias people and their activity were noted well by Fantsur (Barus) and Sibolga people (both are [[Batak]) during their trade.
