Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
ty nang » ky nang, ty hang, ly nang
van cau » van hau, van chat, toan cau
van dau » van dao, phan dau
xuc van » duc van, luc van, vuc van
van van » van ban, tan van, san van
van tri » van tai, van thi, van toi
cua tuc » cua duc, cua tu, cua thuoc

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 ((ty nang) or (ty xang)) xa hoi. lieu ((van cau) OR (van dau)) xuc van van tri cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty nang) OR (ty xang)) xa hoi. lieu ((van cau) OR (van dau)) xuc van van tri cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty nang) or (ty xang)) xa hoi. lieu ((van cau) OR (van dau)) xuc van van tri cua tuc".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty nang) or (ty xang)) xa hoi. lieu ((van cau) OR (van dau)) xuc van van tri cua tuc*.
