Localization for Yahoo Weather (in Chinese)?

Hi Everyone,

Im using and embedding the Yahoo Weather Badge on a chinese website, and the language should also be in chinese.
Does anyone know how to make the language into Chinese (Traditional/Simplified) like the Temp,Day, and other weather information.
or is Yahoo have available localization for it?

Here's an example of the weather badge, parameter for location and country is available,  however i can not find parameters for language.
q=<?php echo $location_id.",".$country_id; ?>&u=c&t=green&l=vertical"

I tried to insert '&lang=zn-ch' but its not working.
q=<?php echo $location_id.",".$country_id; ?>&u=c&t=green&l=vertical&lang=zn-ch"

<iframe allowtransparency="true" marginwidth="0" marginheight="0" hspace="0" vspace="0" frameborder="0" scrolling="no" src="http://in.weather.yahoo.com/badge/?q=<?php echo $location_id.",".$country_id; ?>&u=c&t=green&l=vertical" height="255px" width="186px"></iframe>

Can you anyone help me with this?
Any comments and/or suggestions will be much appreciated.


Thanks and regards,
Chad
