Perhaps you should try some spelling variations:
luc tieng » hoc tieng
tu tieng » tu tuong, tu trong
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
truc va » thuc va, thuc vat, trung va
han tai » hang tai, nhan tai, van tai
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cai
va han » va phan, van han, va hanh

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) OR (ve cham)) truc va han tai ((tu tieng) or (luc tieng))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) truc va han tai ((tu tieng) OR (luc tieng)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) truc va han tai ((tu tieng) or (luc tieng))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ((ve cam) OR (ve cham)) truc va han tai ((tu tieng) or (luc tieng))*.
