"Master, Ran Shixiong's sister-in-law Bai Chunhan, do you know each other?"

"I know, I know all the people who live in this area."

"Did Bai Chunhan call?"

"Nope."

After saying goodbye to the old man, Liu Dayu continued to walk north, and on the opposite side of the school, there was a clock shop, and the name of the watch shop was "Li Ji Clock". A two-square-meter window is filled with a variety of clocks.

As soon as you enter the watch shop, you will be greeted by a counter about one meter high, with a telephone on the counter, and a master is sitting at the counter repairing his watch, wearing a special glasses on his left eye, a watch in his left hand, and a small tweezer in his right hand.

Seeing someone enter the door, the old man put down the things in his hand and took off his glasses: "Comrade, do you repair your watch?" ”

"Master, I'm sorry to disturb you."

"Is there anything you can do?"

"Master, I want to ask you something."

"What do you want to inquire about?"

"Just now- did anyone call you for half an hour?"

"Yes -- three people called."

"Do you know them?"

"They are teachers and students from the opposite school: one teacher, two students."

"Has anyone called before them?"

"No more, after lunch, only three people came to call."

Liu Dayu thanked the old man and went straight to the back street.

At the intersection of East Street and Back Street, Liu Dayu and Li Wenhua met head-on.

Li Wenhua was sweating profusely: "Captain Liu, Bai Chunhan called in the villain bookstore. ”

"Who is the call for?"

"I don't know, the owner of the villain bookstore was busy at the time. His phone was placed outside the bookstore, and the boss didn't hear what Bai Chunhan said. ”

"How long has the phone been running?"

"My wife said that it would be about two or three minutes, and I don't know when I left."

"Doesn't there be a charge for the phone at the villain's bookstore?"

"Bai Chunhan put five cents on the counter and left, so the boss didn't look at the time - looking at the time was to collect money, and since he overpaid, he didn't need to look at the time."

"Did you meet Bai Chunhan on the road?"

"Nope."

The two quickly returned to the backyard of the Ran family.

When the two of them walked out of the third aisle, they saw Bai Chunhan washing rice and vegetables by the well.

The two men walked to the well.

"Bai Chunhan, you put the things on your hands for a while."

"You're looking for me?"

"Yes, we'll ask you a few questions." Liu Dayu said.

Bai Chunhan stood up unhurriedly and wiped the water on his hands with a scarf: "What do you want to ask?" ”

"What did you just do?"

"What do I do, this is my freedom, do you care?"

"We're on official business, so if you don't find it convenient to talk here, you can find another place."

Bai Chunhan shook his long hair, crooked his mouth and exhaled into his nostrils: "I went to the vegetable market to buy vegetables just now, and I made a phone call by the way." What's wrong? ”

"Who is the call to?"

"Call me a good friend."

"What's this friend's name?"

Bai Chunhan smiled slightly: "Her name is Zhao Yuhua." ”

"Where are we going to find her?"

"Is it illegal to make a phone call?"

"Whether it's illegal or not, we'll find out if we check it."

"She works in the library of the District Palace of Culture."

"What did you all talk about?"

"I asked her to go to the Dawn Cinema tonight to watch a movie."
