민망
In 1830, an envoy was dispatched to Qing China. The envoy had a secret mission- to obtain manuscripts of "Ming Shilu" from China. It is estimated that the Vietnamese obtained the manuscript in 1833. Then, Minh Mạng ordered the draft to be rewritten following the writing style of "Ming Shilu". The new version was completed and handed over to the emperor in 1835. Still, Minh Mạng was still unsatisfied with its quality; he would personally edit the text later.
