I’ll say something really cliché, but it can make money on Xianyu:

a beverage display cabinet.
My friend set it up and made 30k yuan in a month.
When the weather gets hot, convenience stores, milk tea shops, barbecue places, mahjong rooms, pool halls—everyone needs refrigerated cabinets and ice chests.
New cabinets are expensive, so many small shop owners don’t want to buy them. They end up going to Xianyu to look for used ones.
But the awkward part is that suitable used cabinets are often located in other cities.
For something this big, once you add up shipping costs, it’s directly not as good as buying new.
That’s when you go to Pinduoduo to search for beverage cabinets—the supply is everywhere, with prices ranging from a few hundred to over 1,000, which is cheaper than many offline quotes.
The method is pretty blunt:
List beverage cabinets and ice chests on Xianyu.
When someone asks, connect them to Pinduoduo suppliers.
This item has a higher per-order price, and profit per order is much more comfortable than with ordinary small goods—making a few hundred isn’t unusual.
The downside too: it’s bulky, and logistics and after-sales service are a hassle.
But precisely because it’s troublesome, many people can’t be bothered to deal with it, so competition isn’t as extreme.
Lots of people spend their days studying small items worth dozens of yuan.
In the end, the ones that can really make money are usually extremely unremarkable-looking.
