Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
thanh lai » thanh lap, thanh loi, thanh tai
su triet » su viet, su tien, ve triet
vien cac » vien bach, vien dai, vien da
nang co » nang cao, nang doc, nang noi
bach ky » bac ky
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
co hoi » co hoc, co loi

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

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