Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
chieu xanh » chieu sach, chieu sang, chieu tinh
ho chieu » theo chieu, hoc thieu, doi chieu
tinh cua » trinh cua, tinh chat, tranh cua
sinh cua » manh cua, dinh cuu, sinh va
dan than » ban than, van than, dan toan
dan chan » dan gian, dan ca, van chat

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((tinh cua) OR (sinh cua)) nhung cong ((dan than) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((tinh cua) OR (sinh cua)) nhung cong ((dan than) or (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((tinh cua) OR (sinh cua)) nhung cong ((dan than) or (dan chan)) cau*.
