As far as I know, Huaibei Senior Dining Hall doesn't need a card to eat. The dining hall for the elderly is designed to provide convenient, affordable and nutritious catering services for the elderly. Generally, only the elderly need to provide identification and a certain fee. In Huaibei City, the elderly can learn relevant information through the community, village committees and other channels and eat in the elderly canteen.

The reason why I gave this answer is because the dining hall for the elderly is a catering place provided by the government or social organizations for the elderly. Its purpose is to facilitate the elderly to eat and provide a nutritious and healthy diet, so there is no need to apply for a card to eat.

If the elderly want to eat in the dining hall for the elderly, they can consult the local community or village committee to find out the specific dining time, place, cost and other information. In addition, the elderly can also learn relevant information through their children or relatives. If the elderly have special dietary needs, they can contact the staff in the dining hall for the elderly in advance so that they can provide corresponding services.

In short, the dining hall for the elderly is a place that provides convenient, affordable and nutritious catering services for the elderly. The elderly only need to provide identification and a certain fee to eat, and they don't need to apply for a card to eat.
