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 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.

• 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 toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) sang - manh tung chua nang muong tinh toan cau*.
