Perhaps you should try some spelling variations:
phan cong » thanh cong
hanh tang » hanh trang, anh tang, hanh mang
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chu manh, chieu xanh, chua xang
tang cua » mang cua, hang cua, tang luan
van cong » van dong, van phong, van duong
toan cao » toan ban, toan tap
chu van » cuu van, chu han

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: chao ((chu xanh) OR (chu van)) - hanh tang cua ((van cong) OR (phan cong)) manh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) or (chu van)) - hanh tang cua ((van cong) OR (phan cong)) manh toan cao~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chu van)) - hanh tang cua ((van cong) OR (phan cong)) manh toan cao*.
