Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh trinh » canh tranh, hanh chinh
hien xanh » hien hanh, hien nhanh, chieu xanh
hanh nang » ganh nang, hanh mang, hanh trang
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
anh nang » ganh nang, anh bang, anh dang
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 nang) OR (anh nang))) OR (hanh trinh)) va nhung cong doan phan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((((hanh nang) or (anh nang))) or (hanh trinh)) va nhung cong doan phan cau*.
