Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
vai cua » dai cua, hai cua, lai cua
nang ma » tang ma, sang ma, nang cao
vi cua » di cua
luc va » duc va, tuc va, loc va
tu sai » tu bai, tu san, tu cai
va cam » va cham, va cac, va cao
sai ky » sac 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.

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