Perhaps you should try some spelling variations:
sach dao » lanh dao
dao dang » cao dang, da dang, dao dong
manh hai » lanh hai, minh hai, thanh hai
te sach » toc sach
hai cuu » hai cua, hai chu, hai cuc
dang xa » dang xay, lang xa, dang ha
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc 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 dang xa hoi. hieu ((ve cai) or (va cac)) ((xuc va) OR (luc va)) manh hai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach dao dang xa hoi. hieu ((ve cai) OR (va cac)) ((xuc va) OR (luc va)) manh hai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach dao dang xa hoi. hieu ((ve cai) or (va cac)) ((xuc va) OR (luc va)) manh hai cuu tre*".
