Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh dat » thanh san, thanh hai, thanh van
hanh dao » lanh dao, thanh dam, doanh dao
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cham » va chat, va tham
tu sac » tu sach, tu san, tu bac
soc va » hoc va, loc va, doc va

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

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