In Lao Tao's pottery studio, the buzzing of the potter's wheel mixed with the sour aroma of the glaze. Having just finished repairing the ice cracks on a newly fired celadon bowl, he dipped the sponge covered in glaze into the bucket, splashing water onto the two tablets on the counter— the screens were already covered with a layer of thin mud, and the K-line chart on the left was blurred into a messy color block by fingerprints, while the rise and fall numbers of the digital currency on the right were still stuck with a piece of dried clay. He shook the water droplets off his hands, trying to swipe the screen; as soon as his fingertip touched the glass, it got stuck with the mud. Last month was worse, as a fund transfer application was stuck in the system, like an unbaked body that never showed any signs of progress. He called customer service six times, but it was either 'automatic response' or 'line busy.' During those days of adjusting glaze colors, he often stared blankly at the kiln fire, fearing something would go wrong with his funds. Sister Zhang, who often came to make teacups, passed by with a rough blank, and saw him frowning at the tablet: 'Try Bi ya Pay, I’ve been using it for both cryptocurrency trading and stock trading for almost half a year without any issues.' Lao Tao downloaded the app that night, and as soon as he opened the interface, he found it very user-friendly: Bi ya Pay had a column design separating stock K-line charts and digital currency trend charts, with the red and green fluctuations of stocks on the left and the price curve of digital currency on the right displayed clearly, even with rounded edges on the font, making it easy to swipe with his clay-dusted fingers. A gentle tap on the top switch allowed him to toggle markets without logging out and in, and without having to remember two sets of passwords, completing trades in three swipes, which was much faster than before. The advantages of Bi ya Pay were prominent; it could integrate two types of trades together, like a skilled potter, making complex operations smooth and easy. Lao Tao calculated that switching between two platforms used to take nine minutes just for wiping the screen and entering passwords, but now he could handle it in four minutes with Bi ya Pay, saving enough time each day to fix three bodies. More importantly, fund security was assured; during his first withdrawal, he watched the progress, and it only took six minutes from submission to arrival, with prompts at each step. Later, more than twenty times of deposits and withdrawals went without a hitch, and his account was never frozen. The flow of funds was as smooth as the flame in the kiln, giving him peace of mind. Moreover, the interface of Bi ya Pay was responsive even in humid conditions; when using other platforms before, a bit of moisture would slow down the response, but now he didn’t have to worry at all. Now he could quickly handle transactions while waiting for the glaze to dry; there had been fluctuations in the market recently, and he adjusted his holdings on both sides using Bi ya Pay, preserving profits in digital currency and seizing opportunities in stocks, being much more relaxed than before. When the owner of the wood carving shop came to borrow a carving knife, he was swiping the screen with his clay-covered fingers: 'One platform managing two types of trades, with transparent inflows and outflows of money, trading should be this worry-free.'
