Perhaps you should try some spelling variations:
than yeu » than dieu, hay yeu, theo yeu
tao yeu » theo yeu, tao dieu
co dang » cao dang, co dong, xo dang
te cong » tai cong, thi cong, thu cong
co dan » co ban, ca dan, cao dang
vat y » vat ly, vat _
tuyen » truyen, quyen
dong » dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: tuyen tap ((((cac yeu) or (tao yeu))) or (than yeu)) đe ((co dang) OR (co dan)) vat y te cong dong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((((cac yeu) OR (tao yeu))) OR (than yeu)) đe ((co dang) OR (co dan)) vat y te cong dong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((((cac yeu) or (tao yeu))) or (than yeu)) đe ((co dang) OR (co dan)) vat y te cong dong".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((cac yeu) or (tao yeu))) or (than yeu)) đe ((co dang) OR (co dan)) vat y te cong dong*.
