Why the Report page language can not be in Chinese

Dear experts,

My customers language is Chinese, but when I log on SRM 7.03, it shows Chinese except the report page.

it is like this:

while if I change to German, the report page can show German.

I searched the discussions before and can not find the solution, and also in the table POWL_QUERY_T , there is Chinese language description for the SRM report part, but no ones in BI report parts.

Can you help me ?

Thanks

Regards,

Hayashi.
