The emergence of online stores has also stimulated the development of the express delivery industry in the Special Economic Zone.

As for the packaging of express delivery, Wei Minsheng put forward his own suggestions.

Most of the packaging is made of uniform-sized boxes made of recycled plastic.

The largest cube is one meter and two squares, known as G1, which means the largest parcel box.

Then the smaller sizes are G2, G3, G4, G5 and G6, with side lengths of 59 cm, 29.5 cm, 14.5 cm, 7.2 cm and 3.5 cm respectively.

These standardized plastic boxes can be nested within each other, and the larger box can fit eight smaller boxes tightly for easy transportation.

What's more, boxes made of recycled plastic can be reused multiple times, making it easy to reshape even if they are damaged.

This approach not only reduces the pressure on the environment of plastic packaging bags, but also reduces the impact on the environment in the production process of paper packaging.

In order to facilitate handling, large plastic boxes with specifications of G4 or higher are ...... Or it should be said that it is a plastic box, leaving some small holes in the appropriate position on the four sides, which is convenient for fingers to focus on, and will not add protruding parts outside the box to affect the nesting packaging.

For people who specialize in express work, there is also a special hook with flat ropes at both ends, which is very convenient and labor-saving for one person or multiple people to carry together.

For products with special shapes that cannot be met by these standard plastic boxes, more suitable packaging materials are selected.

There is just one requirement, the material of the packaging must be recyclable and reusable to reduce the environmental impact.

With everyone working day and night, the main project of the City of Hope continues to extend outward.

The first circle of accommodation has been completed, and eight sub-districts have been initially formed.

With the expansion of the accommodation area, the original delivery method, because there is no unified gate number, people who are not familiar with it do not know where to send these goods, and often need to communicate with each other many times to confirm the direction.

The lack of standard addresses has seriously restricted the improvement of express delivery efficiency.

After referring to many relevant rules on the naming of streets and alleys in China, Wei Minsheng felt that none of them met his needs.

A standard address serves as a basic piece of information for determining the location in everyday life and work, and is often used for people who are not familiar with the local situation.

Therefore, the description of the address should be as simple as possible, and it should be easier to communicate.

Although GPS can also achieve the purpose of precise positioning, it has a fatal problem, that is, it cannot represent the height of the floor.

Moreover, in the floor, the GPS positioning effect is very poor, which is easy to affect the positioning results.

In addition, in terms of communication, the representation of latitude and longitude is not suitable for daily communication.

A long list of numbers, both memorized and described, is overly complex.

Therefore, after carefully studying the urban units that have been repaired in the other world, Wei Minsheng determined his own unique method of compiling the number of the gatehouse in combination with the special structure of the urban unit.

Since the main road of the entire urban unit is built according to the orientation.

Therefore, Wei Minsheng took the street facing the direction of the rising sun in the east as the standard, and set the eight main roads in a clockwise direction to be numbered with eight numbers from "0" to "7".

The streets facing east are called "Avenue 0", and the four even-numbered avenues 0, 2, 4, and 6 correspond to the four positive directions of east, south, west, and north.

Odd-numbered avenues correspond to four auxiliary directions.

The six octagonal roads of the urban unit divide each avenue into six sections, each of which is represented by "0" to "5" from the inside to the outside.

Therefore, "00" represents the first section of due east avenue, and "25" indicates the outermost section of due south avenue.

The six regular octagonal avenues are represented by "A" to "F".

Therefore, "0F" means the section of the Sixth Ring Road that is next to the Oriental Avenue in a clockwise direction.

"2B" means the second ring road that is clockwise along due south avenue.

The first number indicates the avenue, and the second, if it is also a number, indicates the segments on this avenue.

The second number, if it is a letter, indicates an octagonal section of the avenue that runs clockwise.

In this way, only two characters are needed to represent each section of the main road for the entire urban unit.

Moreover, anyone can quickly get to where they want to go according to the signs at the intersection.

For example, if a person's current location is "2B", and he wants to go to the "0F" section, he only needs to walk two avenues counterclockwise to reach the "0B" intersection, and then follow the "0th avenue" and walk four loops outside to reach the "0F" section.

He can also take "Avenue 2" to Ring F first, and then walk counterclockwise along Ring F through two avenues to "0F", which is a relatively long distance.

Of course, there are many more ways to quickly determine your current location and the general direction of the target address without navigation, and plan multiple paths at the same time.

After determining the name of the road segment, it is also necessary to determine the exact house number.

But Wei Minsheng feels that there are many human factors in the compilation of one door and one card in those cities in China, and different people may make up different numbers.

And the messier the house, the more confusing the house number becomes, and it is impossible for an unfamiliar person to quickly determine its location based on an address.

Therefore, Wei Minsheng wanted to use another standardized way to determine a relatively precise location.

Since the size of the urban unit has already been decided, the longest of each section is less than 400 meters.

A section of the road includes two sidewalks, and the total length will not exceed 800 meters.

In view of the house number hanging on the wall, which is easy to be damaged or obscured by the decoration of the façade, Wei Minsheng directly marked the floor tiles on the sidewalk.

From the beginning of the road section to the end direction, left single and right, with three digits to indicate the exact address on the road section.

Each number is spaced two metres apart, and the odd and even numbers together correspond to the scale of the section.

From the number, you can know how many meters it is from the beginning of the section.

At any façade or pedestrian intersection, you can choose the most appropriate number as the house number address.

This way, all frontage addresses can be covered with just five characters.

After determining the address facing the street, the building number is determined clockwise from the main entrance and exit of the community.

Then, directly facing the entrance of the stairway, determine the unit number from left to right, as well as the floor number of each unit.

Finally, go out of the stairs and write the account number clockwise from left to right.

The whole number representing an accurate address is a total of 12 characters, of which the street number number is three characters, the unit number is one character, and the others are two characters.

If you want to find the address of "0D0800831202", first find the starting point of the "0D" section, then walk 80 meters along the "0D" section to find the gate of the community, then find Unit 3 of Building 8 clockwise, and finally No. 2 on the 12th floor.

All urban units have the same main structure regardless of the details, so the same address representation can be used, the only difference is that the name or number of the urban unit is different.
