+# Sample Douyin
+
+## Introduction
+A simple Douyin service built with `Kitex` and `Hertz` which is divided into seven microservices.
+
+| Service Name | Usage                    | Framework   | protocol | Path         | IDL                 |
+|--------------|--------------------------|-------------|----------|--------------|---------------------|
+| api          | HTTP interface           | kitex/hertz | http     | cmd/api      | idl/api.thrift      |
+| user         | user data management     | kitex/gorm  | thrift   | cmd/user     | idl/user.thrift     |
+| video        | video data management    | kitex/gorm  | thrift   | cmd/video    | idl/video.thrift    |
+| favorite     | favorite data management | kitex/gorm  | thrift   | cmd/favorite | idl/favorite.thrift |
+| comment      | comment data management  | kitex/gorm  | thrift   | cmd/comment  | idl/comment.thrift  |
+| message      | message data management  | kitex/gorm  | thrift   | cmd/message  | idl/message.thrift  |
+| relation     | relation data management | kitex/gorm  | thrift   | cmd/relation | idl/relation.thrift |

+### Architecture
+
+![Architecture](./images/architecture.jpg)
+
+### Call Relations
+
+![Call Relations](./images/call-relation.jpg)
+
+### Basic Features
+
+- Hertz
+  - Use `Hertz` binding and validate
+  - Use `obs-opentelemetry` and `jarger` for `tracing`, `metrics`, `logging`
+  - Middleware
+    - Use `requestid`, `jwt`, `recovery`, `gzip`
+- Kitex
+  - User `thrift` IDL to define `RPC` interface
+  - Use `kitex` to generate code
+  - Use `obs-opentelemetry` and `jarger` for `tracing`, `metrics`, `logging`
+  - Use `registry-etcd` for service discovery and register

+```go
+Endpoint = "oss-c**************cs.com"
+AKID     = "LTAI****************92kxo"
+AKS      = "SmEa**************LuS9N3K9"
+Bucket   = "douy******************67"
+CDNURL   = "http://*************.cn/"
+```
