共享 (gòng xiǎng) means 'to share' in the sense of jointly using or having access to something, like resources, facilities, or information (e.g., 共享经济 'sharing economy'). It differs from 分享 (fēn xiǎng), which is about sharing experiences, feelings, or personal items with others. 共享 emphasizes common use, while 分享 emphasizes distributing or giving a part.
