Perhaps you should try some spelling variations:
van lanh » van anh, van hanh, van manh
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
xuc van » duc van, luc van, vuc van
cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sac ky » cac ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sai ky) OR (sac ky)) lang xa hoi. hieu va cac xuc van lanh dao ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sai ky) OR (sac ky)) lang xa hoi. hieu va cac xuc van lanh dao ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sai ky) OR (sac ky)) lang xa hoi. hieu va cac xuc van lanh dao ((cua tre) or (cuu tre))*".
