Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cau treo » cau theo, cau tren, cau triet
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
vai cau » va cau, van cau, vai cac
y nang » ky nang, ly nang, v nang
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
xuc va » tuc va, luc va, xac va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) or (duc va)) hanh vai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) OR (duc va)) hanh vai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) or (duc va)) hanh vai cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ((ve cam) OR (ve cac)) ((xuc va) or (duc va)) hanh vai cau treo*.
