Perhaps you should try some spelling variations:
phap sinh » phau sinh, phai sinh
phap tinh » phap tieng, phap tang, tap tinh
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
anh nang » ganh nang, anh bang, anh dang
cua dang » cua cong
toan cao » toan ban, toan tap

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((phap sinh) or (phap tinh)) - anh nang ((cua dang) OR (cua ban)) cong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((phap sinh) OR (phap tinh)) - anh nang ((cua dang) OR (cua ban)) cong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((phap sinh) or (phap tinh)) - anh nang ((cua dang) OR (cua ban)) cong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((phap sinh) or (phap tinh)) - anh nang ((cua dang) OR (cua ban)) cong manh toan cao*.
