The drop shipping process is as follows:

The customer places an order for you, and then you find your supplier to place an order. The supplier helps you ship the goods and sends them to the freight forwarder near the address of Shopee's logistics warehouse. The freight forwarder then helps you paste the international waybill and sort the goods. Then it helps you send them to the warehouse. The warehouse scans and the shipment is completed~~

So your operation process should be:

First choose your supplier, then determine your warehouse, and choose the nearest warehouse to ship, because Shopee has requirements for delivery time. Then choose a reliable freight forwarder to connect with. Freight forwarders are everywhere, so don't worry about not finding them. There are a lot of them on Taobao. At the very least, I can recommend a reliable one to you.
