Perhaps you should try some spelling variations:
thanh moi » thanh loi, thanh hoa, thanh hai
va triet » va thiet, va trien, ve triet
pham duy » pham duc
hanh moi » hanh noi, hanh mot, hanh mo
cham duc » pham duc, cham soc, phan duc
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
ty nang » ky nang, ty xang, ty hang
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 ty nang x hoi. hieu ve ((cham duc) or (pham duy)) va ((hanh moi) OR (thanh moi)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang x hoi. hieu ve ((cham duc) OR (pham duy)) va ((hanh moi) OR (thanh moi)) va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang x hoi. hieu ve ((cham duc) or (pham duy)) va ((hanh moi) OR (thanh moi)) va triet*".
