Chinese internet giant Tencent Holdings Ltd launched "mini apps" on Monday, which let users interact with app-like services within its instant messaging app WeChat, without having to download and install them. 

国内互联网巨头腾讯公司于1月9日发布“小程序”，可以让用户无需下载和安装便可在微信内互动使用各类程序服务。

Users just need to scan the QR code or search from their WeChat accounts to open these apps, where they could book tickets or do shopping, Tencent said. 

腾讯表示，用户只需在微信中通过扫描二维码或搜索的方式打开这些程序，享受订票或在线购物服务。
