Perhaps you should try some spelling variations:
thanh tung » thanh cong
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
chi xanh » chi anh, chi danh, chi hanh
ca thong » ca thuong, va thong, sau thong
ca trong » cay trong, cad trong, co trong
doi chi » doi khi

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: doi chi xanh - thanh tung ((ca thong) OR (ca trong)) cong doan phan tu~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh tung ((ca thong) or (ca trong)) cong doan phan tu*.
