If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
ArkTS 语言
Stage 应用模型
OpenHarmony 应用开发
分布式软总线
多端部署
AtomGit 仓库管理
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是做出可用应用，而是要让 OpenHarmony 技术特性实质提升方案：评审会看多端部署，以及分布式软总线、分布式数据管理、分布式任务调度或设备虚拟化等能力。提交还需同时准备开源源码、Hap 包、详细说明文档和演示视频；入围决赛后还要细化文档并提交路演 PPT。
This guide is the best pre-read if you want a cleaner start instead of trial-and-error.
