Perhaps you should try some spelling variations:
cua phuong » cuu phuong, luan phuong, xuan phuong
cuc phuong » cac phuong, cuu phuong, chuc thuong
hien xanh » hien hanh, hien nhanh, chieu xanh
hanh tang » hanh trang, anh tang, hanh mang
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cao » toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - hanh tang ((cua phuong) OR (cuc phuong)) cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - hanh tang ((cua phuong) OR (cuc phuong)) cong tan toan cao*.
