Perhaps you should try some spelling variations:
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
nhung cong » dung cong, thong cong, hang cong
khi xanh » khia canh, thi hanh, thi anh
cong san » cong tac
san tuan » van tuan, san luan, san quan
tuan tai » toan tai, quan tai, tan tai

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 - hanh ((truong cua) OR (truong cao)) nhung cong san tuan tai~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh ((truong cua) OR (truong cao)) nhung cong san tuan tai*.
