Perhaps you should try some spelling variations:
tang tai » hang tai, dung tai, sang tao
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
ky tang » ky nang, ky dang, kho tang
tai hai » thi hai, dai hai, tai ha
tu sai » tu bai, tu san, tu cai
loc va » hoc va, luc va
va cam » va cham, va cac, va cao
sai ky » sac ky
ve cam » ve cham, ve cac, ve cai

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 tang tai hai. hieu ((ve cam) OR (va cam)) loc va ((thanh vi) OR (thanh ve)) cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky tang tai hai. hieu ((ve cam) or (va cam)) loc va ((thanh vi) OR (thanh ve)) cua vat~".
• Adding a wildcard symbol may retrieve word variants: tu sai ky tang tai hai. hieu ((ve cam) or (va cam)) loc va ((thanh vi) OR (thanh ve)) cua vat*.
