Perhaps you should try some spelling variations:
truong cong » trong cong, truong long, truong chung
truong dong » trong dong, truong dang, tuong dong
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
dan khan » dan khanh, dan chan, dan than
khan cap » khan ap, than cap, khoan cam
ho lieu » so lieu, ho kieu, ho chieu
co lieu » cot lieu, co hieu, so lieu

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 lieu) OR (co lieu)) tinh - hanh trinh cua ((truong cong) OR (truong dong)) dan khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) or (co lieu)) tinh - hanh trinh cua ((truong cong) OR (truong dong)) dan khan cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) or (co lieu)) tinh - hanh trinh cua ((truong cong) OR (truong dong)) dan khan cap*.
