Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
lanh sang » anh sang, lanh bang, doanh sang
dung cong » dung trong
khi xanh » khia canh, thi hanh, thi anh
anh dang » anh dong, anh dung, anh bang
dan toan » van toan, dan than, manh toan
toan ban » van ban

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 - ((lanh sang) or (anh dang)) va ((nhung cong) OR (dung cong)) dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi khi xanh - ((lanh sang) OR (anh dang)) va ((nhung cong) OR (dung cong)) dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi khi xanh - ((lanh sang) or (anh dang)) va ((nhung cong) OR (dung cong)) dan toan ban*".
