1. Before purchasing goods or after placing an order, contact the customer service or express delivery company in JD.COM in advance to inform that there is no elevator on the second floor, so that the delivery staff can be arranged to adapt to the situation and make preparations in advance.
2. You can ask the deliveryman for help to see if you can help send the goods to the second floor. Some deliverymen are willing to help, but they should be based on the actual situation and the deliveryman's willingness.
