Xianyu, also known as the 'Idle Fish,' is a online C2C (consumer-to-consumer) marketplace application in China operated by Alibaba Group. Most users on Xianyu are individual sellers(C), but there is also a portion of professional sellers(B) who may have much larger transaction volumes.
The "Best Seller Leaderboard"feature ranks professional sellers within each industry based on customer feedback, sales volume, and other metrics, encouraging a competitive and quality-focused marketplace.
A leaderboard that conveys honor and joy
Background Lottie Animation
The animation consists of two parts: when the feature is first launched, the crown appears; when staying on the page, the crown floats and twinkles in loop.

After scrolling down a certain distance, there is a button to return to the top with one click.

A memorable experience
After Launch
Since my internship has ended, I don't have access to the event tracking data. I would like to know more about user data if possible in the future, such as page dwell time and click-through rates, to optimize the design.
The new version was launched in Nov 2023, and I am thrilled to play a significant role in this project. However, due to NDA constraints, I cannot present more design process, but if you're interested, please feel free to contact me for a deeper discussion.
Project Takeaways
Visual Skills
Visuals are also a part of UI/UX, and by creating engaging visual designs, we can enhance the emotional connection with the users.
Cross Function
This project involved animation and much text. Only through communication with copywriters and developers could we determine what kind of design was better.
