I will install a plugin for you,which have Baidu share button.
Is a plugin that can install in your wordpress,so you no need to modify any coding in your site.
And easy to manage in the future,in case you have any ammendment next time.
Place the sharing icons and buttons in any Widget area or use a shortcode to add them to any area in your content.
I understand Chinese very well,I am a Chinese in Malaysia.
See you
