1. The Chinese sturgeon has hard scales on its body surface, and its tail is curved like a shuttle.

2. Habitual behavior

3. After watching Old Things in the South of the City intermittently, the scene is intermittent.

Faint words, quietly revealed, not deliberately carved, slowly flowing into an unfinished poem. I saw old Beijing in the 1920s, the alleys of old Beijing, and those big eyes full of innocence in the alleys were enough to hold all the curiosity and questions in the world. Eiko, a kind and sincere little girl, said goodbye to her childhood when her father's flowers fell, but her childhood was like a mystery, and she remained in her simple world with the passing of some people and things.

Eiko's world is pure and beautiful. She never closes her mind. People of different shapes and confused things shuttled freely in her childhood.

Eiko's eyes are transparent, transparent without any impurities. She looked at the crazy Xiuzhen in Hui 'an Pavilion, unlike people wearing colored glasses. Only she understands the madman's truth and that there is really a "little cassia seed" born in osmanthus fragrance. She gave the watch to Xiaoguizi, because Xiaoguizi could take it home to tell the time. This simplest and simplest way expresses Eiko's seemingly illogical wishes, but it is so reasonable.

Because of this innocence, Eiko is destined to have an indissoluble bond with Xiuzhen's mother and daughter. The small laurel found by Eiko is actually her good friend girl. Since God has a heart of pity, why did he urge the relatives who were worried about day and night to recognize each other, and finally let the rain ruin the dream of reunion? When Eiko woke up from her nightmare, she had moved away. The sound of the train must be so heavy that it can't be removed from the memory of this seven-or eight-year-old child.

No matter how transparent the mind is, it is impossible to see right and wrong in this complex world.

"I can't tell the big sea and the sky. I can't tell the good guys from the bad guys. "

Yes, in Eiko's eyes, there are too many people, and it is difficult to distinguish between good people and bad people. What is a thief like? What is a thief like? Maybe the bad guys should look different from the good guys! Can the young man with thick lips whom I met in the weeds be considered a good man? Why else did you book a "let's go to see the sea" date! And the smiling man wearing a straw hat is so kind after asking for the bronze Buddha, and naturally he is a "good man" in Eiko's view. When the disguised "plainclothes son" solved the case, in the end, the young man who didn't look like a thief became a thief, and he could only become a bad guy under everyone's finger pointing. Eiko, good guys and bad guys, good and evil, right and wrong, what do you see? How did the thief finish his unfinished business?

There were too many puzzles in Eiko's childhood to find the answer: Why did Ma Song go home to be a wet nurse? Why did the money go to someone else? How did the little embolus die? How could a little girl give it to someone else? Finally, Ma Song rode home on a donkey. She wanted to live their lives with her yellow teeth. Yes, life goes on.

Childhood can't go on! The oleander has fallen, and Eiko has grown up, so she can no longer be a child. ...

Faint words, feeling not weak, with a sad taste, leisurely floating in that long time. Thinking silently, unforgettable confusion and sadness, air-dried into a childhood knot.

In order to covet his own selfish desires, Bai disguised himself as a kind person three times, which shows his greed and cunning.
