Launchpad Designer language zh-Hans

Hi experts,

In my Launchpad designer, i logon on as ZH language.

Then i choose a catalog, create a new tile, the brower(Chrome) inform me that

"You can not change Page in language zh-Hans. Original language: zh".

i open F12, in console i write down

sap.ui.getCore().getConfiguration().getLanguage(); click 'Enter" button.

I got "zh-Hans". why is 'zh-Hans'? i obviously logon on as 'zh'.

How can i change to 'zh', then i can create a new tile? any hit? thank you.

Regards,

Archer
