Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh xuat » trinh luat, trinh xuan, trich xuat
nang duong » nang luong, nang dong, tang duong
duong manh » duong van
tieu xanh » tieu danh, chieu xanh, dieu hanh
xuat nang » xuan nang, xuat nong, suat nang
toan cao » toan ban
toan tap » toan ban

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: theo tieu xanh - hanh trinh xuat nang duong manh ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh trinh xuat nang duong manh ((toan cao) or (toan tap))*.
