1) How did you migrate from one domain to another one? Use the Duplicator plugin to move from one domain to another one with a replacement domain in all the necessary places in the DB to the new one. If you replace information in DB tables manually you may face issues with the broken headers or something because the data there is very sensitive.
You did not provide any attachment or link to your screenshot, so I’m not very sure what images are still wrong. Are you talking about the header logo? Then go to Theme Options > Header builder > remover the logo and add that again, save settings.
2) Follow the docs to translate the theme and also the XStore core plugin https://xstore.helpscoutdocs.com/article/30-base-theme-translation
We already have some Chinese translations, so you can download these translations and place them to appropriate folders https://www.8theme.com/glotpress/projects/xstore/
Or provide us with WP Dashboard access and we’ll help you with this.
