Perhaps you should try some spelling variations:
thien van » thi van
ve triet » va trien, su triet
hanh dai » hanh tai, hanh dao, vanh dai
va hanh » van hanh, va thanh, va danh
cac loc » cac lop, cac toc, cac hoc
nang xa » nang x, lang xa, nang ma
loc va » hoc va, luc va
tu san » thu san, tu ban, tu can
dai ve » dap ve, dau ve, dai va
tu sac » tu sach, tu cac, tu bac

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky nang xa hoi. ((lieu va) OR (thien van)) cac loc va hanh dai ve triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ky nang xa hoi. ((lieu va) or (thien van)) cac loc va hanh dai ve triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu san)) ky nang xa hoi. ((lieu va) or (thien van)) cac loc va hanh dai ve triet*.
