Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
chat huu » pham huu
chat xuc » cam xuc, chao xu, chat cua
te sach » toc sach
dai cuu » dai cua, dai huu
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
hieu va » lieu va, hieu qua
y nang » ky nang, ly nang, v nang
o hai » co hai, so hai, o lai
o hoi » co hoi, o hoc, o hoa

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ((o hoi) or (o hai)). hieu va ((chat xuc) OR (chat huu)) va hanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((o hoi) OR (o hai)). hieu va ((chat xuc) OR (chat huu)) va hanh dai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((o hoi) or (o hai)). hieu va ((chat xuc) OR (chat huu)) va hanh dai cuu tre*".
