#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’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
