Hmm, on a whim, I started a book giveaway. Actually it was done in advance.

   Everyone on Sina Weibo, search: - turtle is not a turtle.

  This is Turtle's Sina Weibo account, follow this account, find the Weibo account of Turtle's book giving activity on August 13th at around 3 pm, forward it + 3 friends, and then you can participate in the lottery. There are a total of 10 places, but the number of participants should not be too many, and the chance of winning is still quite high. If the forwarding volume is large, increase it.

   The prize is a physical book signed by Turtle.

   Of course... As a turtle who uses computer code all day long, it is certain that the characters are ugly. If you don't want to sign, you can just drop the physical book. (To be continued~^~)
