Perhaps you should try some spelling variations:
thanh toan » thanh hoa, thanh san, tinh toan
thanh than » thanh thanh, thanh thang, thanh phan
hieu van » hieu va, thien van, lieu va
toc sac » toc sach, toc san, hoc sach
van cam » van nam, van lam, van cau
nang xa » lang xa, nang ma, mang xa
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky
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 cam xuc va ((thanh than) OR (thanh toan)) 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 cam xuc va ((thanh than) OR (thanh toan)) 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 cam xuc va ((thanh than) OR (thanh toan)) cua te".
• Adding a wildcard symbol may retrieve word variants: toc sac ky ((nang xa) or (nang x)) hoi. hieu van cam xuc va ((thanh than) OR (thanh toan)) cua te*.
