1. Competitive pressure: The station is a crowded place. Not only jewelry merchants will set up shop here, but many other types of merchants will also choose to do business here. Therefore, opening a jewelry store in the station will face fierce competition and need to compete with other businesses to attract consumers' attention.

2. High rental cost: The rental cost of opening a shop at the station is usually high. Because there is a large flow of people in this place, it can bring more traffic and exposure to the merchants, so the owners usually raise the rent. For jewelry stores, high rental costs will cause great financial pressure on businesses, and they need to pay higher costs to maintain their operations and profits.

3. Space limitation: The shops in the station are often relatively small and the space is limited. Therefore, the exhibition area in the jewelry store is relatively small, and it is impossible to display too many kinds of products, which will limit the sales and income of the merchants.
