Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
chieu tinh » trieu tinh, lieu tinh, chau tinh
phuong dan » phuong danh, phuong doan, huong dan
doi chieu » doc hieu, doi chi, ho chieu
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap
anh va » hanh va

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 tinh - canh ((anh va) OR (((dinh van) OR (sinh vat)))) nhung phuong dan toan cao~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - canh ((anh va) or (((dinh van) or (sinh vat)))) nhung phuong dan toan cao*.
