in Chinese records changed over time. In the late seventh century, the Buddhist monk Yi Jing mentioned encountering three Chinese monks who lived in a place named Lang-jia-shu (郎伽戍). A Song Dynasty work Zhu fan zhi (published in 1225) gives a description of the country of Ling-ya-si-jia (凌牙斯加). It mentions that its people cut their hair and wrapped themselves in a piece of cloth, its products included elephant tusks, rhinoceros horns, types of wood and camphor, and their merchants traded in wine, rice, silk and porcelain. It also says that the country paid tribute to a country named Sanfoqi, which is usually interpreted to be Srivijaya. Langkasuka was known as "Long-ya-xi-jiao" (龍牙犀角) in Daoyi Zhilüe from the Yuan Dynasty (1279–1368); and "Lang-xi-jia" (狼西加) during the Ming Dynasty (1368–1644), as marked in the Mao Kun map of Admiral Zheng He . Daoyi Zhilüe mentions that the native of Langkasuka make salt from seawater and ferment rice wine, and produced hornbill casques, lakawood, honey and gharuwood. The people wore cotton from the Philippines and printed cloth from India and local sources. "Langkasuka" was mentioned in the Malay text Hikayat Merong Mahawangsa, and it was referred to as "Lengkasuka" in the Javanese poem Nagarakretagama. Tamil sources name "Ilangasoka" as one of Rajendra Chola's conquests in his expedition against the Srivijaya empire. It was described as a kingdom that was "undaunted in fierce battles". Thai sources made no reference to Langkasuka, but Pattani was identified as one of the twelve Naksat cities under the influence of Nakhon Si Thammarat in Thai chronicles. Outline of Langkasuka's history A brief outline of the history of Langkasuka can be determined from the limited historical records available. The kingdom is thought to have been founded some time early in the 2nd century AD. It then underwent a period of decline due to the expansion of Funan in the early 3rd century. In the 6th century it experienced a resurgence and began to send emissaries to China. King Bhagadatta first established relations with China in 515 AD, with further embassies sent in 523, 531 and 568. By the 8th century it had probably come under the control of the rising Srivijaya empire. In 1025 it was attacked by the armies of King Rajendra Chola in his campaign against Srivijaya. In the 12th century Langkasuka was a tributary to Srivijaya. The kingdom declined and how it ended is unknown. Around
