Perhaps you should try some spelling variations:
hanh thoi » hanh thuoc, nhanh thai, hanh noi
hanh hoi » hanh noi, hanh hoa, hanh moi
cua tre » cua te, cuu tre, cua triet
ky sang » ky nang, ky dang, ky tang
sang xa » song xa, lang xa, sang ma
hieu ve » hieu va, hieu van
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
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 sac ky sang xa hoi. hieu ve cac ((xuc va) or (duc va)) ((hanh hoi) OR (hanh thoi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky sang xa hoi. hieu ve cac ((xuc va) OR (duc va)) ((hanh hoi) OR (hanh thoi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky sang xa hoi. hieu ve cac ((xuc va) or (duc va)) ((hanh hoi) OR (hanh thoi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky sang xa hoi. hieu ve cac ((xuc va) or (duc va)) ((hanh hoi) OR (hanh thoi)) cua tre*.
