Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh lay » thanh lap, thanh tay, thanh lam
khach ky » hanh ky, thanh ky
va thanh » gia thanh, ban thanh, va tinh
vu khach » vu khanh, vu khac, vay khach
cuu tre » cua tre, cau tren, cau treo
ve cam » ve cham, ve cac, ve cai
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cac, va cao
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu khach ky nang x hoi. hieu ((ve cam) OR (va cam)) tuc va thanh lay ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach ky nang x hoi. hieu ((ve cam) OR (va cam)) tuc va thanh lay ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach ky nang x hoi. hieu ((ve cam) OR (va cam)) tuc va thanh lay ((cuu tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: vu khach ky nang x hoi. hieu ((ve cam) OR (va cam)) tuc va thanh lay ((cuu tre) or (cua triet))*.
