Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cuu tre » cua tre, cau tren, cau treo
sang ma » nang ma, sang tao, mang may
vai cuu » vai cua
tang ma » mang may, tang van
va hanh » van hanh, va thanh, va danh
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
ve cam » ve cham, va cam, ve cai

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

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