Perhaps you should try some spelling variations:
tinh thanh » dinh thanh, tinh toan, tinh hinh
minh thanh » dinh thanh, hinh thanh, kinh thanh
chuc te » thuc te, chuc ke, chuc theo
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
cam suc » cam xuc, cao suc, cham soc
sac ky » sai ky
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sac ky) or (cac ky)) lang xa hoi. hieu ve cam suc ((minh thanh) OR (tinh thanh)) hoi chuc te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) lang xa hoi. hieu ve cam suc ((minh thanh) OR (tinh thanh)) hoi chuc te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (cac ky)) lang xa hoi. hieu ve cam suc ((minh thanh) OR (tinh thanh)) hoi chuc te".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (cac ky)) lang xa hoi. hieu ve cam suc ((minh thanh) OR (tinh thanh)) hoi chuc te*.
