Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
phuc nang » chuc nang, phuc hang, phuc nhung
lanh manh » lanh tranh, lan anh, anh anh
chu xanh » chu manh, chieu xanh, chua xang
van manh » van minh, van anh, van hanh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
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: theo ((chu xanh) OR (phuc nang)) - ((lanh manh) OR (van manh)) va nhung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (phuc nang)) - ((lanh manh) OR (van manh)) va nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (phuc nang)) - ((lanh manh) OR (van manh)) va nhung cong dan toan cau*.
