Perhaps you should try some spelling variations:
hang tai » hang va, dung tai
hanh tai » thanh tai, han tai, hinh tai
thuc va » thuc vat, thuc dan, thuc day
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
van hac » van hoc, van ha, van hai
van cac » van cau, van bac, dan cac
nang xa » nang x, lang xa, nang ma
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: vu sach ky nang xa hoi. hieu ((van cac) or (van hac)) thuc va ((hanh tai) OR (hang tai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang xa hoi. hieu ((van cac) OR (van hac)) thuc va ((hanh tai) OR (hang tai)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang xa hoi. hieu ((van cac) or (van hac)) thuc va ((hanh tai) OR (hang tai)) cua te*".
