Perhaps you should try some spelling variations:
thanh than » thanh thanh, thanh thang, thanh toan
hieu van » hieu va, thien van, lieu va
than cua » nhan cua, thai cua, ban cua
toc sac » toc sach, toc san, hoc sach
van cau » van dau, van hau, van chat
nang xa » lang xa, nang ma, mang xa
sac ky » cac ky, sai ky
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
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: toc sac ky ((nang xa) or (nang x)) hoi. hieu van cau ((xuc va) OR (tuc va)) thanh than cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky ((nang xa) OR (nang x)) hoi. hieu van cau ((xuc va) OR (tuc va)) thanh than cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky ((nang xa) or (nang x)) hoi. hieu van cau ((xuc va) OR (tuc va)) thanh than cua te".
• Adding a wildcard symbol may retrieve word variants: toc sac ky ((nang xa) or (nang x)) hoi. hieu van cau ((xuc va) OR (tuc va)) thanh than cua te*.
