#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。

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
