theme localization

I am using the WPML plugin for multilingual CMS. I need translation of all strings including “Read more” links. The following locales are needed es_ES, pt_PT, ru_RU, it_IT, and a Chinese locale. I am using the u-design theme. I saw some tutorials but could not follow them. WPML passes the language parameter as ?lang=es for spanish. I have the po and mo files in a subfolder called locale in u-design theme folder.

The site url is https://abgcorp.com/

Could someone please help with this?

Thanks
