[程序咨询] Can I add more languages?

I used your system in Thailand and I want to translate this system to my local language. How can I translate them?

Thank you very much for your use.
You can add a language pack below the folder below, where 'ZH_CN' is Chinese.
1./wmcms/lang/ [system language pack]
2./wmcms/action/xxx/lang [request language pack]
3./module/xxx/lang/ [Module Language Pack]

I added files and folders that location. But it not show on general setting.

You also need to manage the configuration, manage the 'lang' and then edit the results.
Add a Thai option!

Can you give me instructions on how to do this step by step for me?

The way I said on the 4 floor was that I didn't make myself clear

I'm so sorry. I not strong in Chinese. I don't know where to edit it. It's have many Chinese in your system that I still not translate. Anyway, I will retry to find the way for fix it.
Thanks.
