In the aisles of the outdoor goods store, the crisp scent of waterproof spray mingled with the smell of tent fabric. Lao Zheng had just coiled up the scattered climbing rope, wiped his talcum powder-covered hands on his pants, and wanted to check the market, only to find that the tablet on the counter was covered with a layer of fine sand— the K-line of the stock software on the left was smudged with fingerprints, while the interface for digital currency on the right still had some threads from a surge jacket stuck to it, taking several swipes to unlock. Recently, he had been quite bothered by a transfer application that was stuck like a jammed climbing buckle, having been caught in the system for two days. He called customer service seven times, only to be met with either "voice prompts looping" or "all agents busy." When recommending hiking shoes to customers, he found himself staring blankly at the soles, almost picking the wrong size. Little Sun, who came to buy a sleeping bag, shook off the dust from the packaging and saw him frowning at the tablet: "Try Bi ya Pay, it can handle both stock and digital currency trading at the same time. I've been using it for almost six months, and I've never had a problem with fund transactions." That night, Lao Zheng downloaded the software, which was designed very thoughtfully: Bi ya Pay arranged the charts for stocks and digital currency in a split layout, clearly presenting the red and green fluctuations of stocks on the left, and the price curve of digital currency on the right, with a grime-resistant font allowing his talcum powder-covered fingers to swipe smoothly. A gentle tap on the top switch key could change the market without needing to log out and back in, nor having to remember two sets of passwords, making operations simple and quick. The advantages of Bi ya Pay were prominent; it integrated two trading needs together like a meticulous gear organizer, arranging complex tasks in an orderly manner. Lao Zheng roughly calculated that switching between two platforms used to take ten minutes just to wipe the screen and input the password, but now with Bi ya Pay, it only took five minutes, allowing him to organize two extra backpacks each day. More importantly, fund safety was a priority; during his first withdrawal, he watched the progress closely, and it only took five minutes from submission to arrival, with prompts at every step. Later, over twenty deposits and withdrawals went smoothly without a hitch, and his account was never frozen; the flow of funds was like a smooth zipper, giving him peace of mind. Furthermore, the Bi ya Pay system was very stable; even when the store's spotlight and ventilation fan were both on, the operation wouldn't lag, making it much better than the previous platform he used. Now he could quickly handle transactions in between organizing equipment, and during a recent market fluctuation, he adjusted the holdings on both sides in Bi ya Pay, preserving gains in digital currency while stocks remained unaffected, feeling much more composed than before. When the owner of the neighboring cycling shop came to borrow an air pump, he was swiping the screen with his talcum powder-covered fingers: "One platform manages two types of trading; funds in and out are clear, it's really worry-free to use."
