Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung tuan » trung thanh, trung tam, tran tuan
thang long » thanh cong
hieu manh » chieu xanh, hieu nganh, hien hanh
hang nong » han tong
nang phat » nang suat, van phat
phat cau » phan cau, pha cau, phap cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hieu manh) or (dieu hanh)) - thanh trung tuan ((hang nong) OR (thang long)) nang phat cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (dieu hanh)) - thanh trung tuan ((hang nong) OR (thang long)) nang phat cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (dieu hanh)) - thanh trung tuan ((hang nong) OR (thang long)) nang phat cau*".
