One simple rule
Open the page that matches what you actually want.
It is easy to open the biggest AllChinaBuy spreadsheet first and then spend ten minutes scrolling. If you already want shoes, sneakers, bags, hoodies, watches, jerseys, or electronics, start with that product family.
The broad page is still useful when you are browsing for random finds. It is less useful when you already know the item type, size concern, or shipping weight range.
