Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
huong cua » dung cua
chu xanh » chieu xanh, chua xang, chuc danh
chu manh » ho manh, chu han, chu van
hang cua » mang cua, hang ca, thong cua
cong san » cong tac
san than » sang than, san thanh, ban than
than ban » thanh ban, toan ban, than man

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: theo ((chu xanh) OR (chu manh)) - hanh ((hang cua) OR (huong cua)) thong cong san than ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chu manh)) - hanh ((hang cua) OR (huong cua)) thong cong san than ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chu manh)) - hanh ((hang cua) OR (huong cua)) thong cong san than ban*.
