-Flink CDC is a streaming data integration tool that aims to provide users with
-a more robust API. It allows users to describe their ETL pipeline logic via YAML
-elegantly and help users automatically generating customized Flink operators and
-submitting job. Flink CDC prioritizes optimizing the task submission process and
-offers enhanced functionalities such as schema evolution, data transformation,
-full database synchronization and exactly-once semantic.
+Flink CDC 是一个基于流的数据集成工具，旨在为用户提供一套功能更加全面的编程接口（API）。
+该工具使得用户能够以 YAML 配置文件的形式，优雅地定义其 ETL（Extract, Transform, Load）流程，并协助用户自动化生成定制化的 Flink 算子并且提交 Flink 作业。
+Flink CDC 在任务提交过程中进行了优化，并且增加了一些高级特性，如表结构变更自动同步（Schema Evolution）、数据转换（Data Transformation）、整库同步（Full Database Synchronization）以及 精确一次（Exactly-once）语义。
 
-Deeply integrated with and powered by Apache Flink, Flink CDC provides:
+Flink CDC 深度集成并由 Apache Flink 驱动，提供以下核心功能：
+* ✅ 端到端的数据集成框架
+* ✅ 为数据集成的用户提供了易于构建作业的 API
+* ✅ 支持在 Source 和 Sink 中处理多个表
+* ✅ 整库同步
+* ✅具备表结构变更自动同步的能力（Schema Evolution），
 
-* ✅ End-to-end data integration framework
-* ✅ API for data integration users to build jobs easily
-* ✅ Multi-table support in Source / Sink
-* ✅ Synchronization of entire databases
-* ✅ Schema evolution capability

-## How to Use Flink CDC
+Flink CDC 提供了基于 `YAML` 格式的用户 API，更适合于数据集成场景。以下是一个 `YAML` 文件的示例，它定义了一个数据管道(Pipeline)，该Pipeline从 MySQL 捕获实时变更，并将它们同步到 Apache Doris：
