As far as the recorded naming of "Nha Trang" is concerned, in "Toàn tập Thiên Nam Tứ Chí Lộ Đồ Thư", a geographical book written by a Vietnamese scholar with the family of Đỗ Bá in the second half of the 18th century, the name "Nha Trang Môn" ("Nha Trang gate") was mentioned. In another map dating to the 17th century, known as "Giáp Ngọ Niên Bình Nam Đồ" by a noble called Đoan Quận công Bùi Thế Đạt, the name "Nha Trang Hải môn" (Nha Trang Sea Gate) was also cited. In Vietnamese recorded historic bibliographies, these books are perhaps the earliest ones that mentioned this place name.
