#Clear Priorities and Highlight Key Points
Every page must have a clear key focus so users can quickly understand the content of the interface whenever a new page is opened. After you determine the key focus, try to minimize the disruption to your users from unnecessary elements that are not relevant to users' decisions and operations in the page.
#Clear information hierarchy
Each page must obey the following requirements when designing:
1. Users can differentiate primary and secondary information in the view
2. The hierarchies of information in the same view should not be too much
3. Separate the hierarchies of primary and secondary information
#Clear interface operation
Operation buttons in the interface help users to quickly understand and avoid interference factors irrelevant to users' decisions or operations in the page.
