#纪录片
《何以中国》（B站，宣传片），偏考古向的纪录片，讲述史前到秦代文明的历史，追溯中华文明的根基、发源与早期形成和发展。由于这段历史很多部分是没有文字记载的，所以辅之以相应的考古发现，加上拟人化的场景还原。文本台词、摄影都很棒，制作很精美的历史纪录片，我感觉不输以前看过的《河西走廊》。
另外，夏朝的部分一笔带过，看来目前为止的考古发现还没有找到夏朝真实存在过的强有力证据。

Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
