Perhaps you should try some spelling variations:
ve triet » va trien, su triet
tay thai » lay thai, toc thai, y thai
van hanh » van thanh, ban hanh, van anh
dam thuc » am thuc, dan thuc, nam thuc
hieu van » hieu va, thien van, lieu va
tay hoi » tay ho, tao hoi
hanh gi » hanh vi, danh gia, hanh noi
sai ky » sac ky
su sai » su tai, su hai, su dai
gi ve » gia ve, gi de, gi he

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sai ky nang ((tay hoi) OR (tay thai)). hieu van ((dam thuc) or (cam xuc)) van hanh gi ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang ((tay hoi) OR (tay thai)). hieu van ((dam thuc) OR (cam xuc)) van hanh gi ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang ((tay hoi) OR (tay thai)). hieu van ((dam thuc) or (cam xuc)) van hanh gi ve triet".
• Adding a wildcard symbol may retrieve word variants: su sai ky nang ((tay hoi) OR (tay thai)). hieu van ((dam thuc) or (cam xuc)) van hanh gi ve triet*.
