Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
luc bat » suc bat, luc nhat, luat bat
duc ban » duc tan, duc van, dua ban
hanh te » hanh tu, hanh ve, hanh de
cua tre » cuu tre, cua triet, dua tren
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
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: te sac ky nang xa hoi. hieu ve cam ((luc bat) or (duc ban)) hanh te ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ve cam ((luc bat) OR (duc ban)) hanh te ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ve cam ((luc bat) or (duc ban)) hanh te ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ve cam ((luc bat) or (duc ban)) hanh te ((cua tre) OR (cua te))*.
