Perhaps you should try some spelling variations:
thanh thanh » thanh toan, thanh phan, phan thanh
nhanh thanh » phan thanh, nhanh tinh
hieu nganh » vien nganh, hiem ngan, hieu manh
hanh trung » thanh trung, hanh trang, manh trung
dung cong » dung trong
trung ap » trung cap, trung lap, trung tam
ap dung » xay dung, van dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((hieu nganh) or (chinh sach)) - hanh trung ap dung cong ((thanh thanh) OR (nhanh thanh)) cac~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu nganh) OR (chinh sach)) - hanh trung ap dung cong ((thanh thanh) OR (nhanh thanh)) cac*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu nganh) or (chinh sach)) - hanh trung ap dung cong ((thanh thanh) OR (nhanh thanh)) cac*".
