Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
trinh van » trinh han, trinh quan, trinh toan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
trinh va » trinh vat, trinh ve, trinh vi
ban than » ban thanh, van thanh, ban hanh
ban hang » ngan hang

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