Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
banh vai » hanh vi, hanh va, anh va
thu sac » thu sach, thu san, thu xac
van cam » van nam, van lam, van cau
cam cac » ca cac, nam cac, cam chan
cac ban » cac dan, cac van, can ban
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: thu sac ky ((nang x) or (nang cao)) hoi. hieu van cam cac ban ((banh vai) OR (ban va)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang x) OR (nang cao)) hoi. hieu van cam cac ban ((banh vai) OR (ban va)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang x) or (nang cao)) hoi. hieu van cam cac ban ((banh vai) OR (ban va)) cua te*".
