Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
truong cao » truong dai
hien xanh » hien hanh, hien nhanh, chieu xanh
thang cua » thong cua, hang cua, than cua
thanh lap » thanh san, thanh hai, thanh van
cong dan » cong san, cong tan, huong dan
phan lap » phan dau

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 ((thang cua) OR (truong cao)) thuong cong dan ((thanh lap) OR (phan lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh ((thang cua) or (truong cao)) thuong cong dan ((thanh lap) OR (phan lap))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh ((thang cua) or (truong cao)) thuong cong dan ((thanh lap) OR (phan lap))*.
