Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
cap trong » cay trong, ca trong, cad trong
tung cap » trung cap, cung cap, thong cap
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban

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 xanh) OR (chieu tinh)) - thanh tung cap trong cong dan ((toan tai) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - thanh tung cap trong cong dan ((toan tai) or (toan ban))*.
