Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh dao » lanh dao, thanh dat, thanh dam
hanh dai » hanh tai, vanh dai, thanh dat
cham vuc » cham soc, pham duc, cham cuu
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
va cham » va chat, va tham
vuc van » duc van, luc van, thuc van
thu san » thuy san, thu ban, phu san
tu san » tu ban, tu can, vu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu san) or (thu san)) ky lang xa hoi. lieu va cham vuc van ((hanh dai) OR (hanh dao)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (thu san)) ky lang xa hoi. lieu va cham vuc van ((hanh dai) OR (hanh dao)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (thu san)) ky lang xa hoi. lieu va cham vuc van ((hanh dai) OR (hanh dao)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (thu san)) ky lang xa hoi. lieu va cham vuc van ((hanh dai) OR (hanh dao)) cua triet*.
