The Treasure Hunt of an Antique Dealer

On the seventh day after my daughter's first-grade final exam, the class group realized that the summer homework was actually handed in when she returned to school tomorrow. Fortunately, her daughter had already performed well above her level.

But the problem is that a lot of homework, as a junior college student, I actually dig my head and I can't figure out what's going on, **** it!

There are a lot of mistakes, and I am helping her to correct it. It has been more than two hours. I let her go to bed first, and I continue to correct it.

What's wrong with the current education? Are all the tofu dregs in the brains of the experts who made the problem?!

The problem is so rare that I can't solve it!
