Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
phuong thanh » phong thanh, truong thanh, phuong thao
chieu tinh » trieu tinh, lieu tinh, chau tinh
doi chieu » doc hieu, doi chi, ho chieu
toan tai » doanh tai, toan ban, toan cao
toan tap » toan ban
manh va » hanh va, anh va, minh va
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 tinh - canh ((manh va) OR (sinh va)) nhung phuong thanh ((toan tai) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - canh ((manh va) or (sinh va)) nhung phuong thanh ((toan tai) or (toan tap))*.
