Work experience

In the past few years, my career journey has kept evolving. I started as a designer, moved into interaction design, grew into a product designer, and eventually became a product manager.

I have years of team leadership experience at Ant Group, covering AI, engineering efficiency, and program management.

After many years at Ant Group, I founded Mind Bicycle and now serve as Chief Product Officer to build new kinds of product tools.

Some of my life stories

Enjoying life is the source of inner happiness and the motivation to keep improving.

What AI Coding Means for Product Designers

Over the past six months, I've moved significant design work to AI coding. Our profession is undergoing a fundamental restructuring, technical skill is no longer the scarce resource. Judgment is. Designers are shifting from product contributors to product authors....

2025 Annual Summary

This document is both long and short. It is long in terms of the words, filled with the details of 2025. It is short in the context of life, as it represents just a moment of existence....

The meaning of life

Life has no answer key. The past is narrative and the future is projection. The only time you can actually choose, act, and take responsibility is now. Stop waiting for the “better version” of life. Return to what’s workable today: one breath, one conversation, one real step....

The Hidden Complexity of Dark Mode Design

When designing a dark theme, it is not just a simple matter of changing color values; it is a completely new design that involves many potential issues and requires a significant amount of effort....

I Love Obsidian, But We're Not Right for Each Other

Third time trying Obsidian, giving up again. It gives you freedom but also burden. Want to write, end up messing with configs and plugins. Attachments don't make sense, community leans technical. Not that it's bad. We're just not right for each other....

Product principles I believe in

Every product designer should have their own set of principles to hold onto. These beliefs are the result of the years I’ve spent exploring what makes a great designer and a meaningful product.

Why did you become a product designer? What was the first dream that pulled you into this space? The journey will tempt you with ego and distractions, so remind yourself of the original intention every time you make a decision.

We obsess over keeping the experience simple for users, yet we should do the same for ourselves. Clear thinking requires clearing away the unnecessary, otherwise judgement gets lost in noise.

Great products go beyond patching issues. They address the underlying tension so we don't end up fixing the same problem over and over again.

Products aren't just interfaces—they can have a voice, an attitude, and a way to connect emotionally with people. Treat them as living companions to your users.

The pursuit of control often leads to unnecessary complexity. Define what matters, deliver just enough, and give the experience room to breathe.

Products live or die by user trust. Deeply understand their behavior, deliver what matters most, and let reputation compound over time.

Iteration means evaluating honestly. When a feature doesn't deliver, be brave enough to retire it and free the team to build the next right thing.
