With the obvious improvement of China's economic situation, people pay more and more attention to their heath. So we all have some medicine at home. But medicines are plentiful and messy and there are more medicines in stock than there are in stock. Besides, drugs can't be placed at random because it takes up too much space. It is better that we keep the medicine in the medicine cabinet, so the small medicine cabinet at home has become an indispensable article. This is especially true for older people who have difficulty taking care of themselves. As they get older, older people become less healthy and need more medicine every day. Besides, children cannot stay with their parents for a long time, and the elderly can only take care of themselves, and they have to take a lot of medicine every day. Therefore, the management of drugs has become a big problem.
