Cheng-hua: Year 16, Month 7, Day 23
28 Aug 1480
The chieftains Zhao Meng-bu and others who had been sent by Dao San-bao and other native-official pacification superintendents of the Che-li, Laos and Ba-bai/Da-dian Pacification Superintendencies in Yun-nan, came to Court and offered tribute of gold and silver utensils, rhinoceros horn, elephant tusks and other goods. Biao-li of variegated silks were conferred upon each of them. In addition, they were given patterned brocades and variegated silks to confer, on their return, on the native-officials and their wives. At this time, Laos had been attacked and subject to massacres by the Jiao people. The Grand Defender eunuch Qian Neng advised of this. He also requested that consideration be given to providing the tribute envoys sent by Laos, Ba-bai and Che-li with travelling expenses, so that they could travel back quickly. The Ministry of War responded with a supporting memorial. It was ordered that the Yun-nan Provincial Administration Commission provide the envoys from each place with 20 liang of silver from official funds.
