We can't be sure whether there is a lucky draw in every jewelry store at the bus terminal, because the arrangement of activities of each merchant may be different. However, when buying jewelry or other valuables, we should keep a high degree of vigilance and rational thinking, fully verify the qualifications of merchants and the details of various activities, and don't easily believe in exaggerated propaganda and false lottery promises. At the same time, I suggest that you fully understand your own needs before shopping, compare the goods and quality of different businesses, pay attention to the price and after-sales service, and fully protect your rights and interests. If you encounter any problems and doubts in shopping, you should also communicate with merchants or relevant departments in time to solve them and safeguard your own rights and interests and consumers' rights and interests.
