Perhaps you should try some spelling variations:
thanh tung » thanh cong
nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
khi xanh » khia canh, thi hanh, thi anh
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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: "doi khi xanh - ((thanh trung) OR (thanh tung)) cua nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - ((thanh trung) OR (thanh tung)) cua nhung cong tan toan tap*.
