Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
hanh vai » hanh vi, hanh va, hanh tai
sach ly » sach y, sach lo, sach ty
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
ly nang » ky nang, ly hang, ly vang
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
luc va » duc va, tuc va, loc va
x hoi » o hoi, x ho, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ly nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ly nang ((x hoi) OR (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ly nang ((x hoi) or (xa hoi)). hieu ((ve cam) OR (ve cac)) luc va hanh vai cuu tre*".
