Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
cuu tre » cua tre, cau tren, cau treo
va hanh » van hanh, va danh, ban hanh
ky sang » ky nang, ky dang, ky tang
sang ma » tang ma, nang ma, sang tao
vai cuu » vai cua
tu sac » tu sach, tu cac, tu san
va cam » va cham, va cac, va cao
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, ve cai
ma hoi » mai hoi, xa hoi, ma hoa

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