Perhaps you should try some spelling variations:
truong phuong » truong chung, truong trung, dung phuong
nhung phuong » dung phuong, nhu phuong, bang phuong
hanh trung » thanh trung, hanh trang, manh trung
hien xanh » hien hanh, hien nhanh, chieu xanh
thanh cac » hanh cac, thanh bac, thanh ca
trung ha » trung hoc, trung tam, trung cap
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 ((nhung phuong) OR (truong 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 ((nhung phuong) OR (truong phuong)) dan ((than cap) or (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh trung ha ((nhung phuong) OR (truong phuong)) dan ((than cap) or (thanh cac))*.
