Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
te sai » te bai, te lai, te hai
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao

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