Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung dung » phuong dung, ung dung, thong dung
doi chieu » doc hieu, doi chi, ho chieu
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 - manh ((trung cua) OR (trung cap)) ((nhung dung) OR (nhung phuong)) dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - manh ((trung cua) OR (trung cap)) ((nhung dung) or (nhung phuong)) dan than cao~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - manh ((trung cua) OR (trung cap)) ((nhung dung) or (nhung phuong)) dan than cao*.
