Perhaps you should try some spelling variations:
nang muong » nang luong, lang muong, nang truong
muong tinh » duong tinh, muong thanh, khuong tinh
hoc thieu » hoc hien
manh cong » manh cuong, hanh cong, manh long
cong chua » cong cua, cong chuc, con chua
chua nang » chuc nang, chua xang, kha nang
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) sang - manh cong chua nang muong tinh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (toc thieu)) sang - manh cong chua nang muong tinh toan cau*.
