Perhaps you should try some spelling variations:
thuat san » thuat toan, thuat song, thuat lanh
hanh vai » hanh vi, hanh va, hanh tai
cham luc » nhan luc, cham cuu, chat lua
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
hieu ve » hieu va, hieu van
ly nang » ky nang, ly hang, ly vang
cuu tre » cua tre, cau tren, cau treo
san ly » van ly, ban ly
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: thuat san ly nang ((o hoi) or (xa hoi)). hieu ve ((cham luc) OR (cham soc)) va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ly nang ((o hoi) OR (xa hoi)). hieu ve ((cham luc) OR (cham soc)) va hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ly nang ((o hoi) or (xa hoi)). hieu ve ((cham luc) OR (cham soc)) va hanh vai cuu tre*".
