Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
trung ha » trung hoc, trung cap
toan cao » toan ban, toan tap
ho kieu » ho lieu, so kieu, thi kieu
co lieu » cot lieu, co hieu, so lieu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((ho kieu) or (co lieu)) tinh - thanh ((trung ha) OR (trung tam)) nhung cong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho kieu) OR (co lieu)) tinh - thanh ((trung ha) OR (trung tam)) nhung cong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho kieu) or (co lieu)) tinh - thanh ((trung ha) OR (trung tam)) nhung cong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((ho kieu) or (co lieu)) tinh - thanh ((trung ha) OR (trung tam)) nhung cong manh toan cao*.
