Origin of the Idiom: The Return of the Qingfu Coin
The qingfu is a water insect from ancient legend, resembling a cicada but slightly larger, and it is edible. Legend has it that it lays its eggs on blades of grass; if a human takes away its offspring, the mother insect will surely fly thousands of miles to find them.
The method of “paying back the money by the clam” recorded in “Huainan Wanbi Sue” is: smear 81 copper coins with the blood of the mother clam, and another 81 copper coins with the blood of the child clam. When buying things, the mother’s money and the child’s money are used alternately, and the money used out will fly back by itself. In this cycle, the money will never be used up. In the Jin Dynasty, Gan Bao’s “Search of the Supernatural” also recorded this legend, and from then on, “qingfu” became a synonym for money.
The Meaning of the Two Characters “Shou She”
“Shoushe” means to guard the home and remain within it. When combined, the phrase “Qingfu Shoushe” conveys the hope that, like the legendary Qingfu coin, money spent will somehow return on its own—allowing wealth to circulate within the home endlessly, never running dry. It was a popular auspicious saying used in olden times by shops and households to attract and retain fortune.
-Circulation of Wealth: Inspired by the saying “the green moneyfly flies away and then returns,” it means spending money freely, yet it will eventually flow back, ensuring that one’s financial resources never run dry. -Enduring Family Prosperity: In the past, merchants often affixed the auspicious phrase “Green money flies in” to their cash boxes; the name of the time-honored brand “Rui Fuxiang” also derives from this very meaning. https://baike.baidu.com/item/还蚨/0. -Unending Wealth: During the Qing dynasty, folk coins were cast bearing the inscription “Qingfu Gather,” and even modern banknotes featured the qingfu motif, symbolizing prosperity and good fortune. https://baike.baidu.com/item/还蚨/0
Project Background
In the digital age, salary income and consumption expenditure are all active in the numbers on the screen, and there is no real feeling any more. For those who do not plan, it is easy to fall into the consumption trap or debt pressure. After using a variety of bookkeeping APP experiences, they are worried about the sensitive problem of data flow. It coincides with seeing the introduction of AirBuild project and trying to develop the first APP.
Early-stage design asset development with AirBuild
With the help of Lovart’s brand kit, I helped me design the page and Logo of APP, and carried out complete development with the help of AirBuild. The experience in the development process was really great. For some problems that I did not understand IOS development at all and did not understand the adaptation of iPhone models, it didn’t matter. It was good to give AirBuild a team role development, and I had a good experience of being “Party A’s cool feeling” and experiencing every step in the process, including the verification of the design draft, the construction of the development framework, the preview in the development process, the real machine test TestFlight completed by the development, and the final store shelves, although the materials required in the country are a bit complicated due to the verification and APP filing operations. However, it can be directly listed in other regions and is still available for download.

Although some minor adjustments were made during the actual development process, I think it’s already great! At least when I’m developing, I’m too lazy to achieve pixel-perfect fidelity with the design specs—let’s leave that for future iterations.
In the end
It seems that AI has brought many conveniences. Although, for many complex business systems undergoing iteration, it hasn’t yet been tested in a production environment, when developing a completely new business or making an attempt, trusting AI and carefully managing its boundaries can indeed save a lot of effort.
Haha, this is my first time developing an iOS app from scratch—kind of exciting! Here’s the download link for you to check it out.
