Note 6 — Chapter XXXIII
Henry Yule translation
After the death of Kúblái astronomy fell into neglect, and when Hongwu, the first Ming sovereign, took the throne (1368) the subject was almost forgotten. Nor was there any revival till the time of Ching. The latter was a prince who in 1573 associated himself with the astronomer Hing-yun-lu to reform the state of astronomy. (

What Ricci has recorded (in Trigautius) of the dense ignorance of the Chinese literati in astronomical matters is entirely consistent with the preceding statements.
