Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
phuong dan » phuong danh, phuong doan, huong dan
hien xanh » hien hanh, hien nhanh, chieu xanh
trung cap » truong cao, trung tam
thanh cac » hanh cac, thanh bac, thanh ca
trung ha » trung hoc, trung tam
than cap » khan cap, thanh lap, than cua

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: hoc hien xanh - hanh ((trung ha) OR (trung cap)) nhung phuong dan ((than cap) OR (thanh cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh ((trung ha) OR (trung cap)) nhung phuong dan ((than cap) or (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh ((trung ha) OR (trung cap)) nhung phuong dan ((than cap) or (thanh cac))*.
