Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
van hanh » van thanh, ban hanh, van anh
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
va cham » va chat, va tham
duc van » duc va, duc tan, duc manh
vi cua » vai cua, di cua
cua te » cua tu

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 y ((nang xa) OR (lang xa)) hoi. lieu ((va cac) or (va cham)) duc van hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach y ((nang xa) OR (lang xa)) hoi. lieu ((va cac) OR (va cham)) duc van hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach y ((nang xa) OR (lang xa)) hoi. lieu ((va cac) or (va cham)) duc van hanh vi cua te*".
