Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cuu tre » cua tre, cau tren, cau treo
vai cuu » vai cua
hieu ve » hieu va, hieu van
sang ma » nang ma, sang tao, mang may
tang ma » mang may, tang van
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
tu sac » tu sach, tu cac, tu san

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 ma) OR (tang ma)) hoi. hieu ve cam ((xuc va) or (tuc va)) hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang ma) OR (tang ma)) hoi. hieu ve cam ((xuc va) OR (tuc va)) hanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang ma) OR (tang ma)) hoi. hieu ve cam ((xuc va) or (tuc va)) hanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((sang ma) OR (tang ma)) hoi. hieu ve cam ((xuc va) or (tuc va)) hanh vai cuu tre*.
