"Hehe, when I look at Officer Zhang, he rarely plays the numbers game." Seongnam smiled and explained: "Chinese characters cannot represent numbers if they are not certain, and sometimes even a Chinese character can represent various numbers when decoding, of course, this must be under corresponding conditions." ”

"Han Xiao didn't leave us the word mobile phone to remind us to use a digital password to open the stone door, because anyone with a little common sense can see this, and he wants to tell us that if you want to unlock the secret of this note, you need to use a mobile phone." Seongnam paused and continued: "I think Han Xiao should have known that we would go through his things before he died, and he also knew that we would notice this note, but he was afraid that we would not know how to unravel this note, so we should do our best to leave us such a hint. ”

"Ahh After listening to Chengnan's explanation, Zhang Mei was extremely surprised, he didn't expect such a complex logic Chengnan to find out in a meeting, and it was so clear.

"Seongnam you are so powerful, it's a pity that you are not a policeman." Zhang Mei praised sincerely.

"It's just that I still don't understand, what do these numbers represent? How do we know? After Zhang Mei finished praising it, she continued to express her doubts.

"It's actually quite simple." Cheng Nan said and took out his mobile phone, opened the lid, pointed to the buttons on his hand, and said: "Look, the buttons of the mobile phone are actually very simple, in addition to the numbers, each number also has the letters we use to send text messages, so the answer will not come out?" ”

"Are you saying that the pinyin of those four words represents each number of the key?" Zhang Mei is not stupid, Chengnan understood it as soon as she reminded her.

"Well, but we are going to divide it into two now, one is that this password is the number corresponding to the first letter of each of these four words, and the other is the number corresponding to all the letters of the whole spelling letter of these words."

"Huh? If it is the first type, the letter is S-H-G-L, and the corresponding number is 7-4-4-5, and if it is the second type, it is S-H-E-N-G-H-U-N-G-U-I-L-A-I, and the corresponding number is 7-4-3-6-4-4-8-6-4-4-5-2-4. Zhang Mei looked down at Chengnan's mobile phone and calculated, while remembering the calculated numbers in her heart.

"But what set of numbers is this? I think if we guess wrong, we can't be safe, right? Otherwise, people don't have to make such trouble? Zhang Mei kept those numbers firmly in her heart and asked her own questions.
