Perhaps you should try some spelling variations:
trung quan » truong quan, trong quan, trung tuan
dung cong » dung trong
khi xanh » khia canh, thi hanh, thi anh
tung qua » tuong quan, duong qua, thong qua
dung qua » duong qua, dung quan, dung cua
cong anh » cong danh, dong anh, hong anh
tuan tu » tuan thu, tran tu, toan tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: doi khi xanh - thanh ((((tung qua) OR (dung qua))) or (trung quan)) dung cong anh tuan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi khi xanh - thanh ((((tung qua) OR (dung qua))) OR (trung quan)) dung cong anh tuan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi khi xanh - thanh ((((tung qua) OR (dung qua))) or (trung quan)) dung cong anh tuan tu*".
