Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nam thuc » nam thuoc, am thuc, nam thu
thuc van » thuc vat, thuc dan, thuc va
thanh le » thanh ve, thanh de, thanh liem
thinh le » trinh ly
su sach » so sach, vu sach
hiem he » hiem xe, hieu he, thien he
y nang » ly nang, v nang, may nang
he nam » ha nam, nghe nam

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((y nang) or (ky nang)) xa hoi. hiem he nam thuc van ((thanh le) OR (thinh le)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (ky nang)) xa hoi. hiem he nam thuc van ((thanh le) OR (thinh le)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) or (ky nang)) xa hoi. hiem he nam thuc van ((thanh le) OR (thinh le)) cua triet*".
