Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, nhung don
cdinh cua » chinh cua, dinh cuu, sinh cua
hang cong » dang cong, hang nong, bang cong
tren chau » tran chau, tren ca, tren cay
ho chieu » theo chieu, hoc thieu, doi chieu
dinh cua » dinh cuu, sinh cua, dinh cu
tac tren » rac tren, tai tren, tap tren

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: ho chieu sach - hanh ((cdinh cua) OR (dinh cua)) ((nhung cong) OR (hang cong)) tac tren chau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((cdinh cua) or (dinh cua)) ((nhung cong) OR (hang cong)) tac tren chau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((cdinh cua) or (dinh cua)) ((nhung cong) OR (hang cong)) tac tren chau*.
