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
hanh dai » hanh tai, vanh dai, thanh dam
hieu va » lieu va, hieu qua
va cham » va chat, va tham
nang xa » nang x, lang xa, nang ma
soc va » hoc va, loc va, doc va
sac ky » cac ky, sai ky
tu sac » tu sach, tu cac, tu 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 sac ky nang xa hoi. hieu va cham soc va ((hanh dai) or (((hanh dao) OR (thanh dat)))) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va cham soc va ((hanh dai) OR (((hanh dao) OR (thanh dat)))) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va cham soc va ((hanh dai) or (((hanh dao) OR (thanh dat)))) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va cham soc va ((hanh dai) or (((hanh dao) OR (thanh dat)))) cua triet*.
