Perhaps you should try some spelling variations:
kieu tinh » lieu tinh, trieu tinh, bien tinh
chau tinh » cuu tinh, ha tinh, cua tinh
hanh dung » thanh dung, anh dung, hanh dong
cua thong » cua thuong, cua khong, cua tong
thong tan » thong than, thong tran, thong tin
dung cua » dung luan, dung cho
tan toan » tan tran, tap toan, van toan
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 ((((kieu tinh) OR (diep tinh))) OR (chau tinh)) - hanh dung cua thong thong tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho ((((kieu tinh) or (diep tinh))) or (chau tinh)) - hanh dung cua thong thong tan toan cao*.
