Perhaps you should try some spelling variations:
thang long » thanh cong
tang luan » dung luan
tin nang » tin dung, thi nang, van nang
tang cua » mang cua, hang cua, thong cua
long tap » luong tap, tong tap, luong tai
tap doan » tap quan
doan cau » toan cau, doan dau, doan cap
ki nang » ky nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((tin nang) OR (ki nang)) - hanh ((tang cua) or (tang luan)) thang long tap doan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tin nang) OR (ki nang)) - hanh ((tang cua) OR (tang luan)) thang long tap doan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tin nang) OR (ki nang)) - hanh ((tang cua) or (tang luan)) thang long tap doan cau*".
