Chinese (722–723). Another embassy visiting China in 750 came probably from Water Zhēnlà. According to the Chinese Annals a son of the king of Wèndān had visited Chinas in 753 and joined a Chinese army during a campaign against Nanzhao () in the following year. After the Wèndān embassy in the year 771 the heir-apparent Pómí () came to the imperial court and, on 13 December 771, he received there the title "Kaifu Yitong Sansi" (), one of the highest honorific titles. In 799 an envoy from Wèndān called Lītóují () received a Chinese title, too. As rulers of Śambhupura are attested by the inscription K. 124, dated 803/04 a king Indraloka and three successive queens, Nṛpatendradevī, Jayendrabhā and Jyeṣṭhāryā. Two inscriptions refer to a ruler named Jayavarman: the first one, K. 103, hails from Práḥ Thãt Práḥ Srĕi south of Kompoṅ Čàṃ, dated 20 April 770, the second one from Lobŏ'k Srót in the vicinity of Kračèḥ near Śambhupura (K. 134), dated 781. Cœdès called him Jayavarman Ibis, but probably he is identical with Jayavarman II, the founding father of the Angkorian kingdom, as Vickery has pointed out: "Not only was Jayavarman II from the South; more than any other known king, he had particularly close links with Vyādhapura. This place is recorded in only one pre-Angkor inscription, K. 109/655 [exactly: 10th February 656], but in 16 Angkor-period texts, the last dated 1069 [K. 449 from Pàlhàl, dated Sunday, 3rd May 1069] ... Two of them, K. 425/968 and K. 449/1069, are explicit records of Jayavarman II taking people from Vyādhapura to settle in Battambang." Conflicting records According to the inscription from Čăn Năk'ôn in Basăk/Laos (K. 363) Vīravarman was the father of Citrasena (royal title Mahendravarman) who was the younger brother of Bhavavarman. Obviously both princes had the same mother, but different fathers, which was corroborated by the Si Tep inscription (in present-day Thailand) giving the information that Bhavavarman was the son of a Prathivīndravarman and grandson of a Cakravartin whereas the inscription from Pak Mun in Ubon/Thailand informs us that the name of the father of Vīravarman was called Sārvabhauma. All these inscriptions refer to a large territory ruled by these kings. It is recorded in the inscription from Robaṅ Romãs at Īśānapura (the archaeological site of Sambor Prei Kuk) that a certain Narasiṃhagupta, who was vassal (samāntanṛpa) of the successive kings Bhavavarman, Mahendravarman (the ruling name
