Perhaps you should try some spelling variations:
phuong doanh » phuong doan, phuong hoang, phuong anh
phuong danh » phuong anh, phuong dinh, phuong hanh
trinh toan » tinh toan, thanh toan, trinh han
chu tinh » chau tinh, chua tinh, cuu tinh
hoan ban » hoang ban, toan ban, hon ban
ho chu » hoi chu, cho chu, ho chua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chu tinh - hanh ((trinh toan) OR (tinh quang)) nhung ((phuong doanh) OR (phuong danh)) hoan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chu tinh - hanh ((trinh toan) or (tinh quang)) nhung ((phuong doanh) OR (phuong danh)) hoan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chu tinh - hanh ((trinh toan) or (tinh quang)) nhung ((phuong doanh) OR (phuong danh)) hoan ban*.
