Perhaps you should try some spelling variations:
cua quoc » cua thuoc
van hanh » van thanh, ban hanh, van anh
cua nuoc » cua nguoi, cua thuoc, nha nuoc
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, pham duc
hanh tai » thanh tai, hang tai, han tai
te sach » toc sach
sach ty » sach y, sach tu, sach thu
ang xa » lang xa, mang xa, dang xay
ty ang » ty xang, ty hang, ty anh

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ang xa hoi. hieu van ((cham xuc) or (cham soc)) van hanh tai ((cua nuoc) OR (cua quoc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ang xa hoi. hieu van ((cham xuc) OR (cham soc)) van hanh tai ((cua nuoc) OR (cua quoc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ang xa hoi. hieu van ((cham xuc) or (cham soc)) van hanh tai ((cua nuoc) OR (cua quoc))*".
