Perhaps you should try some spelling variations:
thanh cham » thanh pham, thanh cha, hanh cham
hien xanh » hien hanh, hien nhanh, chieu xanh
hanh manh » hanh mang, hoang manh, thanh minh
lanh manh » lanh tranh, lan anh, van manh
tong cong » trong cong, cong cong, dung cong
cua tong » cua cong, cua dong, cua nong
cong san » cong tac
phan cau » phan dau, phan cac, phan tu

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 manh) OR (lanh manh)) cua tong cong san ((thanh cham) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((hanh manh) OR (lanh manh)) cua tong cong san ((thanh cham) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((hanh manh) OR (lanh manh)) cua tong cong san ((thanh cham) or (phan cau))*.
