汪大渊
The only Chinese first-hand account of 14th century Temasek (the name used before it was changed to Singapura), "Dao Yi Zhi Lue" written by Wang Dayuan, indicates that Temasek was ruled by a local chief (before the time of Parameswara). However the word used by Wang indicates that the ruler of Temasek was not independent, rather he was a vassal of another more powerful state.
