Alibaba is an e-commerce platform that brings together a large number of merchants and suppliers. These merchants and suppliers need to abide by the rules and standards on the platform to ensure that the products and services they provide are authentic, reliable, and of high quality.

In addition, Alibaba also provides strict certification and audit mechanisms, such as transactions through Alipay, member verification, gold medal supplier certification, etc. These all provide certain guarantees for consumers. However, due to the large number of merchants and suppliers on Alibaba, consumers still need to choose carefully, pay attention to the merchant's credibility and customer reviews, and avoid being deceived. In general, the things on Alibaba are reliable to a certain extent, but consumers still need to choose carefully.
