The ghost explained, "Below the old doorplate, there are some strange symbols called 'Suzhou numerals,' which represent the numbers from one to ten."

"They correspond to the doorplate numbers above. If the numbers on the old doorplate have been eroded by the wind, you can still get clues about the door number from the Suzhou numerals."

"If there are no Suzhou numerals, but a small circle of characters is written in front of the number, it means that there may have been two batches of doorplates that were almost the same when the doorplate was hung. In order to distinguish them from each other, they added a code on it to represent a larger number."

"This number used to be a code within the industry."

"It was generally used more in old Beijing clothing shops."

"The shop assistants wrote the bottom price in code on a certain part of the second-hand clothes being sold to prevent forgetting, and also to prevent customers from knowing. For example, 'Xiao, Dao, Tiao, Fu, Luo, Jun, Xian, Shi, Wai, Ke' to represent the numbers from one to ten."

"Dao 26, actually should mean number 226."

The ghost said here, and pointed to the address again, "Moreover, this Linghu East Road should be the address used before the city built the reservoir."

"It should go south from here to the top of the mountain, which is not far from the reservoir."

"There is also a hospital there, about an hour's drive from here!"

My brow couldn't help but raise slightly: Is what this old ghost said credible?

The two hospitals are at least thirty or forty kilometers apart, and according to the old man, the hospital there is very remote. Hospitals that are generally built in remote places are either sanatoriums or mental hospitals.

While I was wondering, Feng Ruoxing had already walked behind me and whispered, "Jing Henyun's family is from old Beijing, and they used to be in the second-hand clothing business."

I was stunned again: According to Feng Ruoxing's statement, the other party would come up with such an address because they thought Jing Henyun could understand it.

However, why hasn't Jing Henyun reminded me all this time?

Or, did the person who arranged this address just assume that Jing Henyun could understand it?

I asked casually, "What's the name of the hospital you mentioned? What does it do?"

The ghost said, "That's a mental hospital called Ningkang Hospital. It houses severely mentally ill patients. Moreover, that place has been a place for housing mentally ill people since before the founding of the country."

"I haven't been there either, and I don't know if it's still in use now?"

At this time, another ghost said, "That place is still in use, but I heard that it's haunted. Moreover, it's very haunted. Even the doctors and nurses are not very normal. So no one dares to go, and no one dares to inquire!"

I looked at the other party and said, "You are a ghost yourself, and you don't dare to inquire about ghost affairs?"

The ghost said, "I heard it when I was alive. I also heard that some family members of patients heard that their relatives were killed in the hospital, and they went to the hospital to make trouble."

"After the trouble, they saw their relatives and apologized to the hospital. But after they went back, the family who made trouble died."

"Legend has it that as long as people enter that hospital, they are no longer people of the Yang world."

"People outside can't visit, let alone make trouble. Otherwise, they will all be taken into that hospital."

That ghost said, "Great Immortal, if you really want to go, I can give you a way."

The ghost saw that I didn't object, and said, "That hospital needs someone to clean it every three months, and it only takes care of one cleaning company. They give a very high price."

"If you calculate the days, this week should be the time for the cleaning company to clean the hospital. If you want to go, you can apply to the cleaning company. Otherwise, the hospital will not let you in."

I asked in confusion, "How do you know these things?"

The ghost said, "I used to work at Huasheng Cleaning Company! I also sent cleaners to Ningkang Hospital."

"However, I only sent people to the landmark of Ningkang Hospital and came back. People from the hospital picked them up and went in. After a week, I went to the landmark to pick them up."

"Our boss said that no matter whether you pick up or send people, you can't pass the landmark."

Does a hospital need to set up a landmark?

Landmarks are mostly used to delineate boundaries.

Who does a hospital need to delineate boundaries with?

How did the boss of Huasheng Cleaning get the hospital business?

I stared at the ghost and said, "Tell me, how did you die?"

The ghost thought for a long time: "I don't quite understand. The hospital said I had a sudden heart attack, but I have never had such a medical history."

I said in a deep voice, "What did you see before you died? Do you still remember?"

The ghost said, "I didn't see anything!"

"I just felt someone following me behind when I was walking home. Before I had time to look back, I felt someone push me from behind."

"I fell and never got up again."

I nodded slightly and said, "I understand."
