Perhaps you should try some spelling variations:
sach dao » lanh dao
lanh hai » thanh hai, lang chai, lanh dao
manh hai » minh hai, thanh hai, van hai
te sach » toc sach
va cham » va chat, va tham
xay hoi » xa hoi, tay hoi, cay phoi
dao van » do van, dang van
chu tre » cho tre, chu tri, cuu tre
xuc va » duc va, tuc va, luc va
ve cai » va cai, ve cac, ve tai

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 dao van xay hoi. hieu ((ve cai) or (va cham)) xuc va ((manh hai) OR (lanh hai)) chu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach dao van xay hoi. hieu ((ve cai) OR (va cham)) xuc va ((manh hai) OR (lanh hai)) chu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach dao van xay hoi. hieu ((ve cai) or (va cham)) xuc va ((manh hai) OR (lanh hai)) chu tre*".
