Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
hieu van » hieu va, thien van, lieu va
ky lang » ky nang, ky tang, tay lang
tai cua » thai cua, tai cuc, tri cua
ky dang » ky nang, ky danh
van hau » van ha, van hai, van dau
tuc va » thuc va, truc va, tuc xa
su xac » pu xac, su cac
xuc va » duc va, luc va, xac va
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su xac ((ky lang) OR (ky dang)) xa hoi. hieu van hau ((xuc va) or (tuc va)) thanh tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ((ky lang) OR (ky dang)) xa hoi. hieu van hau ((xuc va) OR (tuc va)) thanh tai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ((ky lang) OR (ky dang)) xa hoi. hieu van hau ((xuc va) or (tuc va)) thanh tai cua te".
• Adding a wildcard symbol may retrieve word variants: su xac ((ky lang) OR (ky dang)) xa hoi. hieu van hau ((xuc va) or (tuc va)) thanh tai cua te*.
