Perhaps you should try some spelling variations:
dang xa » dang xay, lang xa, dang ha
hieu va » lieu va, hieu qua
va cham » va chat, va tham
cuu tre » cua tre, cau tren, cau treo
sac ky » cac ky, sai ky
soc va » hoc va, loc va, doc va
va dan » ca dan, va dao, va dau
dan vi » doan vi, don vi, dan va
vi cuu » vi luu, vinh cuu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sac ky)) dang xa hoi. hieu va cham soc va dan vi cuu tre~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach y) or (sac ky)) dang xa hoi. hieu va cham soc va dan vi cuu tre*.
