Page interactions and information
The starting-point diagnostic and conversation brief run within your current browser page. This site has no business-form endpoint receiving that content and does not automatically send it to the team. The site does not retain it after you close or refresh the page.
External contact services
Phone and Chengquan links open those services; the WeChat button only copies the phone number. If you choose to send information, handling depends on the service and your arrangements with the team. The hosting service may process basic access logs needed to serve pages.
People, images and case studies
Vivi’s career details are based on information she supplied. The portrait is the version supplied and approved by Vivi. Product-workspace and website scenes are AI-generated concepts, not actual client projects. Cases draw on the Chengquan website’s published anonymized team practice, with source links on each case page.
