My girlfriend wants to eat my cooking, but she is in Weinan. What should I do in Jilin? How can I deliver it safely?

Food can't be delivered by express. The most effective way is to cook it yourself, or you can cook it for her when she comes over. Another method is to use refrigerated logistics and deliver it to her when it is ready. Other methods are not recommended, because unless you are vacuum packed, it cannot be delivered.
