Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dung sai » dung tai, dung va, dung dat
danh sai » danh bat, danh dau, hanh san
te sach » toc sach
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va, hieu qua
danh va » doanh va, hanh va, anh va
y nang » ky nang, ly nang, v nang
va am » va lam, va cam
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: te sach y nang x hoi. hieu va am thuc va ((danh va) or (((danh sai) OR (dung sai)))) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu va am thuc va ((danh va) OR (((danh sai) OR (dung sai)))) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu va am thuc va ((danh va) or (((danh sai) OR (dung sai)))) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu va am thuc va ((danh va) or (((danh sai) OR (dung sai)))) cua triet*.
