Perhaps you should try some spelling variations:
tinh dinh » trinh dinh, tinh ninh, tinh binh
te sach » toc sach
va tinh » may tinh
cu treo » cau treo, cau tren
cu tren » tu tren, dua tren
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
o hoi » co hoi, o hoc, o hai

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 (x ho)). lieu va cam xuc va tinh dinh ((cu treo) OR (cu tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((o hoi) OR (x ho)). lieu va cam xuc va tinh dinh ((cu treo) OR (cu tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((o hoi) or (x ho)). lieu va cam xuc va tinh dinh ((cu treo) OR (cu tren))*".
