Wiktionary has dialect maps for common Chinese vocabulary that showcases the differences in terminology across various regions of Chinese, rather than their similarities. Example: sleep -> https://en.wiktionary.org/wiki/Template:zh-dial-map/%E7%9D%A... , hide-and-seek -> https://en.wiktionary.org/wiki/Template:zh-dial-map/%E6%8D%8...

p.s. I'm saying this because most of these terms that has a dial-map are common in daily conversation. The differences in written Chinese vocabulary aren't as significant; how scientific and technical terms are expressed is largely determined by your administrative region.
