Perhaps you should try some spelling variations:
te sach » toc sach
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
van lam » van nam
van cam » van nam, van cau, van dam
ty hang » ly hang, ty xang, thi hang
ty nang » ky nang, ty xang, ly nang
luy tre » luyen tre
vi luy » vi lua, vi luu

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 ((ty nang) or (ty hang)) xa hoi. thi ((van cam) OR (van lam)) duc va danh vi luy tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) xa hoi. thi ((van cam) OR (van lam)) duc va danh vi luy tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ty hang)) xa hoi. thi ((van cam) OR (van lam)) duc va danh vi luy tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) or (ty hang)) xa hoi. thi ((van cam) OR (van lam)) duc va danh vi luy tre*.
