hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
nam luc » nhan luc, nam thuc, nam duoc
va tinh » may tinh
tu sai » tu san, tu cai, tu lai
tu bai » tu ban, tu bat, te bai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sai) OR (tu bai)) ky nang xa hoi. hieu van ((nam luc) or (nang luc)) va tinh viec cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu bai)) ky nang xa hoi. hieu van ((nam luc) OR (nang luc)) va tinh viec cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu bai)) ky nang xa hoi. hieu van ((nam luc) or (nang luc)) va tinh viec cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sai) OR (tu bai)) ky nang xa hoi. hieu van ((nam luc) or (nang luc)) va tinh viec cua triet*.
