Perhaps you should try some spelling variations:
muong tinh » muong thanh, khuong tinh, truong tinh
duong tinh » duong minh, duong sinh, dong tinh
hoc thieu » hoc hien
manh tung » manh hung, thanh tung
tung chua » cung chua, cong chua, dung nhua
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 tung chua nang ((muong tinh) OR (duong tinh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (toc thieu)) sang - manh tung chua nang ((muong tinh) OR (duong tinh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (toc thieu)) sang - manh tung chua nang ((muong tinh) OR (duong tinh)) toan cau*.
