Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
lanh trinh » hanh trinh, anh trinh, lanh tranh
hoc thieu » toc thieu
trinh vat » trinh van, trinh luat, sinh vat
hang nong » thang long, han tong
than phan » thanh phan, toan phan, thanh pham
phan cac » nhan cach, phan dau, phan lap

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: ((hoc thieu) OR (hoc hien)) xanh - lanh trinh vat ((nhung cong) OR (hang nong)) than phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) xanh - lanh trinh vat ((nhung cong) or (hang nong)) than phan cac~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (hoc hien)) xanh - lanh trinh vat ((nhung cong) or (hang nong)) than phan cac*.
