Today, I suddenly got the news that the elder of the family passed away, and I was very sad. It stands to reason that I should go back, but I am in a foreign country, and there are many things, so I may not be able to go back, and I am very entangled. There are a lot of things going on today, so I won't change it first, let's change it early tomorrow, please forgive me, it's really sudden.

In addition, I wrote about the wonderful part, and I can't deal with it in a few words because I am in a hurry, so I have enough time to write about it tomorrow to ensure the quality.

"Military Science and Technology" takes a day off and is in the middle of the hand, please wait a while,
