Meituan during CNY?

Will Meituan still operate during/leading up to CNY? I’m in Nanshan, Shenzhen. My colleague warned me to stock up on food for the whole CNY week due to restaurant/supermarket closures, but I’m also seeing online that some things should be open except for the actual day of CNY. Do you think I could order groceries/meals for the actual the day before and be fine? Or do I need to stock up for a whole week? I’m a lazy bum who relies on Meituan for all this ¯\(ツ)/¯
