Wan-li: Year 8, Month Intercalary 4, Day 14
26 May 1580
The pirate Lin Dao-qian had occupied islands in the ocean and was bringing calamities through sudden appearance and rapid disappearance. The generals and troops were unable to apprehend him and he used Patani and Siam as his lairs. Subsequently, he threatened Patani and engaged in violent attacks on Siam, and an interpreter noted that those countries wished to offer their services by capturing him. Liu Yao-hui, the supreme commander of Guang-dong/Guang-xi proposed that a reward for him be again established, as thereby he would certainly be captured. The ministry re-submitted the proposal as a request and the Emperor approved it.
