Perhaps you should try some spelling variations:
truong toan » truong ton, trong toan, truong tan
trung toan » trung tuan, trung tran, trong toan
thong cong » trong cong, tong cong, thong thong
van thanh » ban thanh, van tuan
chao chu » cho chu, cua chu, cao cho
chu xanh » chu manh, chieu xanh, chua xang

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

• Performing a fuzzy search may retrieve terms with similar spellings: chao chu xanh - hanh ((trung toan) OR (truong toan)) thong cong ((xuan toan) or (van thanh)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: chao chu xanh - hanh ((trung toan) OR (truong toan)) thong cong ((xuan toan) OR (van thanh)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu xanh - hanh ((trung toan) OR (truong toan)) thong cong ((xuan toan) or (van thanh)) cau*".
