林悦己 LIN YUEJI / PERSONAL FIELD NOTES
AI turns ideas into reality
I am Lin Yueji (林悦己), head of growth at EvoLink.ai and a hands-on creator of AI content for overseas audiences
I started in data analysis and visualization, then worked on skill services, AI tools for productivity, AI-coded products and AI media accounts abroad
Today I put that experience into one growth path: getting AI models discovered, understood and integrated, until they turn into sustained usage and business results
START HERE / 00
First time here? Start with these
This site is not a content warehouse. It is a map from problems to practice, and on to resources you can reuse
Start with real practice
AI tools, content growth, workflows and going global. I do not write about methods I have not used
Take resources you can use
Prompts, model experiments, courses and information sources, organized by task rather than piled into folders
Meet the person behind the content
From data analysis and market growth to AI content and products for overseas markets: how I built my own system
PROOF FROM THE FIELD / 01
These numbers are not meant to define a person; they show that the method has been used in real conditions
Data as of June 2026. The processes behind them come from publicly posted field reviewsFrom AI content in China to niche overseas accounts, continuously testing topic selection, distribution and cross-platform content
A million views from zero, testing overseas information sources, speed on trends, content expression and platform distribution
From first-hand information gathering and content organization to building and updating the repository, testing AI agent collaboration and open-source content distribution
Taking an AI product from 0 to 1 and earning overseas revenue

RESOURCE LIBRARY / 03
Resources organized by task
Not a large collection for its own sake: only what helps you take the next step
Prompts, Demos and Use Cases
Browse prompts, playable demos and real workflow cases by content type
An AI learning path for non-engineers
From official courses and conceptual intuition to agent practice, with less aimless bookmarking
Tools and first-hand sources
The AI tools, newsletters and channels I keep using to build my own information network
WORKING PRINCIPLES / 04
How I work
Between execution, judgment and systems, there has to be a path that can be run again and again
Get it working, then refine
Build a feel for the problem through real publishing and user feedback, then turn what works into a system
Go back to first-hand sources
Do not settle for second-hand conclusions; keep following official accounts, key people and real user communities
Make content modular
Design topic selection, research, scripting, production, distribution and review separately so output can be sustained
Results must be verifiable
Pages, data, links and real API calls all leave evidence; done is not a verbal status
CASE NOTES / 05
