Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
cua nuoc » cua quoc, cua thuoc, nha nuoc
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
tu xang » ty xang, tu lang, tu quang
xang xa » lang xa, mang xa, ang xa
sach tu » sach thu, cach tu, sach ty
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
ve cam » ve cac, va cam, ve cai

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 tu xang xa hoi. hieu ((ve cam) or (ve cham)) xuc van hanh tai ((cua nuoc) OR (cua nguoi))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu xang xa hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh tai ((cua nuoc) OR (cua nguoi)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu xang xa hoi. hieu ((ve cam) or (ve cham)) xuc van hanh tai ((cua nuoc) OR (cua nguoi))".
• Adding a wildcard symbol may retrieve word variants: te sach tu xang xa hoi. hieu ((ve cam) or (ve cham)) xuc van hanh tai ((cua nuoc) OR (cua nguoi))*.
