Perhaps you should try some spelling variations:
thanh tinh » thanh binh, nhanh tinh, than kinh
cau tren » cu tren, dau tren, ca tren
tinh cau » trinh cau, tinh cao, sinh cau
va thanh » gia thanh, ban thanh, va tinh
cac luc » cau luc, coc luc, cac nuoc
te sach » toc sach
xay hoi » xa hoi, tay hoi, cay phoi
hieu va » lieu va
luc va » duc va, tuc va, loc va
tu san » thu san, tu ban, tu can
va xay » va xac

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 san) OR (te sach)) ly va xay hoi. ((hieu va) OR (hieu qua)) cac luc va thanh tinh cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (te sach)) ly va xay hoi. ((hieu va) OR (hieu qua)) cac luc va thanh tinh cau tren~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (te sach)) ly va xay hoi. ((hieu va) OR (hieu qua)) cac luc va thanh tinh cau tren*.
