Perhaps you should try some spelling variations:
tranh chua » tranh cua, trinh chuan, tranh chap
chua nang » chuc nang, chua xang, kha nang
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
song tam » dong tam, duong tam, dong tai
cong tac » cong ty
toan cao » toan ban, toan tap

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: ((ho trieu) OR (25 trieu)) tinh - canh tranh chua nang ((song tam) OR (cong tac)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) or (25 trieu)) tinh - canh tranh chua nang ((song tam) OR (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) or (25 trieu)) tinh - canh tranh chua nang ((song tam) OR (cong tac)) toan cao*.
