Perhaps you should try some spelling variations:
thuat lanh » thuat lap, thuat san
van hanh » van thanh, ban hanh, van anh
tu sach » thu sach, su sach, te sach
xuc van » duc van, luc van, vuc van
va cam » va cham, va cac, va cao
vi cuu » vinh cuu
vi luu » vi lua
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thuat lanh)) ky nang x hoi. lieu va cam xuc van hanh ((vi cuu) OR (vi luu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat lanh)) ky nang x hoi. lieu va cam xuc van hanh ((vi cuu) OR (vi luu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat lanh)) ky nang x hoi. lieu va cam xuc van hanh ((vi cuu) OR (vi luu)) tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat lanh)) ky nang x hoi. lieu va cam xuc van hanh ((vi cuu) OR (vi luu)) tre*.
