Perhaps you should try some spelling variations:
hoang van » hang va
van thanh » ban thanh, van tuan
thanh vi » hanh vi, thanh va, thanh ve
chat soc » cham soc, chat hoc, chat doc
te sach » toc sach
luu tre » cuu tre, luy tre
soc van » hoc van, oc van, sac van
va chat » van chat, va phat, cao chat
sach ky » sac ky, sach y, sach ty
mang xa » lang xa, mang may, dang xay
tru » truc

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((mang xa) or (hoang van)) hoi. lieu va chat soc van thanh vi ((luu tre) OR (luu tru))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((mang xa) OR (hoang van)) hoi. lieu va chat soc van thanh vi ((luu tre) OR (luu tru))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((mang xa) or (hoang van)) hoi. lieu va chat soc van thanh vi ((luu tre) OR (luu tru))*".
