João Rodrigues Tçuzu arrived in Macau from Japan in 1614, 6 years after completing his most famous work about Japanese grammar, Arte da Lingoa de Iapam.

Francisco de Pina drowned at sea in modern Cửa Đại on 15 December 1625 while trying to rescue guests on a wrecked boat.

[4] Pina believed that such skill was a fundamental part of the evangelization work, and repeatedly accused his fellow clergymen of not acting in the same manner.

[6] Some scholars[1][7] have argued that Pina is responsible for writing a grammar based on which Honufer Bürgin compiled and edited the text Manuductio ad Linguam Tunkinensem independently of the work of Alexandre de Rhodes.

[1] Other scholars have challenged this conclusion by gathering evidence that the Manuductio ad Linguam Tunkinensem was written by Philippus Sibin using the Dictionarium Annamiticum Lusitanum et Latinum of Alexandre de Rhodes as a reference.
