Especially in the brewing and drying area, there are hundreds of large vats placed horizontally and vertically, all of which are covered with a large hat woven with bamboo strips, which are used to shield from rainwater, and the air is filled with a strong sauce fragrance, which is wafting out of the sauce vat.

On the north side of the drying area there is a large factory building - that is, the storehouse, the architectural style of this warehouse is very special, except for the blue brick wall, the small black tile roof, the most special thing is that the house is one floor, but the roof ridge is two floors, between the first and second ridges are glass windows, these windows are open - presumably for ventilation. Director Zhen said that the processed pickles should be stored here for a period of time before they can leave the factory.

The pickles were packed in jars of different shapes, large and small, so that in this storehouse there were layers of small jars of different shapes - at least half a man high, and the mouths of these small jars were sealed with lotus leaves. There are trademarks on the jar, what "Jingnan tofu marinade", what "spiced tender cucumber", what "spicy soybean paste", there are many varieties, and so on. Jars of the same model are stacked together, and there is a passage about one meter wide between the jars of different models.

Seven or eight workers are transporting and stacking vegetable jars with trolleys.

Walking out of the back door of the warehouse, you can see a wall more than one person high, Ouyang Ping visually measured it, the height of the wall is about one meter nine, it is made of green bricks, there is a small hall on the wall, the corner of the wall is covered with moss, and there are some dead weeds erected on the top of the small palace. Just from the roof of the small hall on the wall, you can see the long history of the pickle factory.

To the east of the wall, near the Ma Po Nunnery, there are two old-fashioned wooden doors, on which are dozens of iron rivets nailed horizontally, the iron rivets are narrow at both ends and wide in the middle, and have long been rusted.

In the middle of the two wooden doors there is a circular copper plate with a diameter of about 50 centimeters, the circular copper plate is fixed on the wooden door, and an iron latch is welded on the copper plate, and a large lock is hung on the iron latch.

Ouyang Ping looked up at the tallest building in Granny Ma's Nunnery, and could see the windows on the second and third floors of the small building. It is uncertain whether you can see the back door of the pickle factory from the second and third floors of the small building, because there are several old ginkgo trees next to the east wall of the pickle factory.

On either side of the wooden door there is a brick house.

Director Zhen stopped in front of the brick house on the west side of the wooden door: "This is the gatehouse." ”

"Where's Master Gao?"

"At night, the wind is so high that it is here, but during the day, it is difficult to say. Wait a minute, I'll call him - might he be in the workshop to help?" After Director Zhen finished speaking, he strode into the back door of the warehouse.

After about two minutes, Director Zhen ran out of the back door: "It's so high that the wind will be there in a while." I'll take you to the docks first. Director Zhen said as he put his hand into the window -- there were two opposite windows on the south side of the gatehouse -- the windows were open -- the only two windows in the gatehouse.

When Director Zhen's right hand retracted from the iron fence of the window, he held a bunch of keys in his hand. Obviously, the key was hanging next to the window - where the hand could reach it.

"Director Zhen, are these two windows usually open?"

"Yes, it's usually open, and even if it's closed, it can be opened - the latch is never plugged in, what's wrong?"
