🏮 今日正月十五，元宵节快乐
元宵节，又称上元节、小正月、元夕或灯节，南京称小年。正月是农历的元月，古人称“夜”为“宵”，正月十五日是一年中第一个月圆之夜，所以称正月十五为“元宵节”。根据道教“三元”的说法，正月十五日又称为“上元节”
元宵节主要有赏花灯、吃汤圆、猜灯谜、放烟花等一系列传统民俗活动。此外，不少地方元宵节还增加了耍龙灯、耍狮子、踩高跷、划旱船、扭秧歌、打太平鼓等传统民俗表演

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.
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.
