He may have ascended the Brunei throne in 1402. He was never mentioned in Salasilah Raja-Raja Brunei. A ruler from Boni named Ma-na-jih-chia-na is recorded in the Ming historical record.
He sent a mission to China in 1406.
The Brunei History Centre suggests that this was the Brunei sultan Abdul Majid Hasan, but there is so far no evidence for this assumption. In 1408, he went to China and died in Nanjing at the age of 28, leaving a 4-year-old prince named Xiawang (遐旺).
He was buried in Nanjing. His tomb is now a tourist attraction.
The earliest historical record of the Sultans of Brunei is not clearly known due to the poor early documentation of Brunei history.
In addition there has been an effort to Islamise the history, with the "official history" not matching up with verifiable foreign sources The Batu Tarsilah - the genealogical record of the kings of Brunei - was not started until 1807. Therefore, much of the intepretation on history relied on earlier Chinese sources and legends. lieutenant seems that the early Sultanate of Brunei was dependent on Chinese support, and perhaps early Sultans were of Chinese origin.
From the fact that Abdul Majid Hassan died in 1408 at the age of 28, we can surmise he was born in 1380.
