Is the May 1st holiday open? Can we bring food and drinks?

In China, May 1st is a public holiday known as Labor Day (五一劳动节). Many tourist attractions and recreational facilities are open during this period.

Regarding your specific question, it depends on the individual attraction or facility. Some popular sites may allow visitors to bring in outside food and drinks, while others might have restrictions or prohibit it altogether.

Here are some general guidelines:

1. Major theme parks: Most Disney-style amusement parks and other major theme parks permit bringing food and drinks from the outside.
   
2. National parks: Many national parks allow picnics or eating on designated areas.
   
3. Museums: Some museums may not permit inside consumption of food, while others might have a café area where you can eat.
   
4. Restaurants and cafes: Normal restaurants and cafes usually don’t allow customers to bring in outside food.
   

To be sure, it’s always best to check with the attraction or facility directly before visiting during Labor Day (May 1st). You can ask about their policy on bringing outside food and drinks when you book tickets or upon arrival.
