Perhaps you should try some spelling variations:
bang luan » hang luan, dung luan, tong luan
tang luan » dung luan
dung cong » dung trong
chu xanh » chu manh, chieu xanh, chua xang
cong nam » dong nam, uong nam, thong nam
nam toan » nam tan, tam toan, nam thanh
toan cau » toan cao, toan ban, toan tap
chu van » cuu van, chu han

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: chao ((chu xanh) OR (chu van)) - hanh ((bang luan) OR (tang luan)) dung cong nam toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chu xanh) or (chu van)) - hanh ((bang luan) OR (tang luan)) dung cong nam toan cau~".
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chu van)) - hanh ((bang luan) OR (tang luan)) dung cong nam toan cau*.
