Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
truc va » thuc va, thuc vat, trung va
va cam » va cham, va cac, va cao
di cua » dai cua, doi cua, de cua
te sai » te tai, te lai, te hai
ve cam » ve cham, ve cac, ve cai
te bai » te bao, te tai, te ban

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: ((te sai) OR (te bai)) ky nang x ho. hieu ((ve cam) OR (va cam)) truc va hanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sai) OR (te bai)) ky nang x ho. hieu ((ve cam) or (va cam)) truc va hanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sai) OR (te bai)) ky nang x ho. hieu ((ve cam) or (va cam)) truc va hanh di cua tre*.
