Perhaps you should try some spelling variations:
nhung thi » nhung thoi, phung thi, nhung tri
viet tran » viet trang, viet trung, viet thanh
viet tuan » viet thuan, viet quan, viet thanh
trong ban » trong san, trong tan, trong quan
nhung gi » nhung bai
nhung bi » nhung bai
ban hanh » ban hang
que van » qua van, quy van, quyet van

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((nhung gi) or (nhung bi))) or (nhung thi)) que van. ((viet tran) OR (viet tuan)) trong ban hanh~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((nhung gi) OR (nhung bi))) OR (nhung thi)) que van. ((viet tran) OR (viet tuan)) trong ban hanh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((nhung gi) or (nhung bi))) or (nhung thi)) que van. ((viet tran) OR (viet tuan)) trong ban hanh".
• Adding a wildcard symbol may retrieve word variants: ((((nhung gi) or (nhung bi))) or (nhung thi)) que van. ((viet tran) OR (viet tuan)) trong ban hanh*.
