Perhaps you should try some spelling variations:
ve triet » va trien, su triet
xa thanh » va thanh, ha thanh, ta thanh
xa hanh » xa khanh, va hanh, da hanh
su sach » so sach, vu sach
va chat » van chat, va phat, cao chat
nang ma » tang ma, sang ma, nang cao
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
tai ve » tai va, tai he, tai le

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang ma hoi. hieu ((va chat) or (va cac)) xuc ((xa hanh) OR (xa thanh)) tai ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. hieu ((va chat) OR (va cac)) xuc ((xa hanh) OR (xa thanh)) tai ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. hieu ((va chat) or (va cac)) xuc ((xa hanh) OR (xa thanh)) tai ve triet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoi. hieu ((va chat) or (va cac)) xuc ((xa hanh) OR (xa thanh)) tai ve triet*.
