Perhaps you should try some spelling variations:
trong phuong » truong phuong, trong phong, trong phung
phuong tien » phuong trinh
trang cua » tranh cua, trung cua, thang cua
tien toan » thien toan, dien toan, tien thanh
chi xanh » chi anh, chi danh, chi hanh
tang cua » mang cua, hang cua, tang luan
toan cao » toan ban, toan tap
doi chi » doi khi

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: doi chi xanh - hanh ((trang cua) OR (tang cua)) trong phuong tien toan cao~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh ((trang cua) or (tang cua)) trong phuong tien toan cao*.
