Perhaps you should try some spelling variations:
thanh tung » thanh cong
dang cong » dung cong
khi xanh » khia canh, thi hanh, thi anh
tung cua » trung cua, tuong cua, dung cua
cua dang » cua cong, cua ban
tac tren » rac tren, tai tren, tap tren
tac trai » tam trai, khac trai, rac thai

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 tung cua dang cong ((tac tren) OR (((tac trai) OR (tam tri)))) cau~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - thanh tung cua dang cong ((tac tren) OR (((tac trai) OR (tam tri)))) cau*.
