Perhaps you should try some spelling variations:
phuong danh » phuong anh, phuong dinh, phuong hanh
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
phuong dan » phuong doan, huong dan, phuong lan
hanh sinh » hanh tinh, hanh dinh, hinh sinh
toan ban » van ban
sinh va » sinh vat, tinh va, dinh van

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: doi ((chieu xanh) OR (chieu tinh)) - hanh sinh va nhung ((phuong dan) OR (phuong danh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - hanh sinh va nhung ((phuong dan) OR (phuong danh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - hanh sinh va nhung ((phuong dan) OR (phuong danh)) toan ban*.
