Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
cham luc » cham soc, nhan luc, chat lua
cham cuu » cap cuu, chat cua
va doanh » van doanh, va danh, hoa doanh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
tai cua » thai cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
bao ky » cao ky, ban ky, bac ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te bao ky nang xa hoi. hieu va ((cham luc) or (cham cuu)) ((va doanh) OR (vay doanh)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te bao ky nang xa hoi. hieu va ((cham luc) OR (cham cuu)) ((va doanh) OR (vay doanh)) tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bao ky nang xa hoi. hieu va ((cham luc) or (cham cuu)) ((va doanh) OR (vay doanh)) tai cua tre*".
