Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van tham » van thanh, van tuan, van chat
tham soc » cham soc, tham nuoc, thai son
van hanh » van thanh, ban hanh, van anh
dinh cuu » dinh chi
tang xa » trang xa, tang ma, lang xa
soc van » hoc van, oc van, sac van
sac ky » sai ky
vi cuu » vi luu, vinh cuu

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sac ky) OR (cac ky)) tang xa hoi. hieu van tham soc van hanh ((vi cuu) or (dinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (cac ky)) tang xa hoi. hieu van tham soc van hanh ((vi cuu) OR (dinh cuu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (cac ky)) tang xa hoi. hieu van tham soc van hanh ((vi cuu) or (dinh cuu)) tre".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (cac ky)) tang xa hoi. hieu van tham soc van hanh ((vi cuu) or (dinh cuu)) tre*.
