Perhaps you should try some spelling variations:
thieu khang » chieu khong, thieu quang
trinh cong » trinh dung
hoc thieu » toc thieu, hoc hien
tranh qua » tranh cua, thanh qua, trinh qua
qua trinh » qua kinh
dan hang » ban hang, dat hang, dai hang
van hang » van khang, van hoang, van thang

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu khang - canh tranh qua trinh cong ((dan hang) OR (van hang)) va~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu khang - canh tranh qua trinh cong ((dan hang) OR (van hang)) va*.
