## What it is
A curated collection of Go learning examples covering go-kit microservices, gRPC load balancing with etcd, DDD/hexagonal architecture, and utility tools. Each example is paired with detailed Chinese-language blog articles walking through the implementation.

## Use cases
- learn go-kit microservices step by step
- implement gRPC load balancing with etcd service discovery
- understand DDD and hexagonal architecture in Go
- add JWT authentication to a Go microservice
- set up Prometheus monitoring and Jaeger tracing for Go services
- see an OAuth2 authorization code flow implemented in Go
- learn rate limiting and circuit breaking patterns in Go

## When to choose
- you are a Go developer learning microservice architecture through runnable examples
- you want reference implementations of go-kit, gRPC, or DDD patterns
- you prefer examples accompanied by in-depth tutorial articles

## When to avoid
- you need a production-ready framework or library to drop into your project
- you want a maintained, supported product rather than educational code
- you need English-language documentation
