• 关于运费：
  When ordering a large quantity, it is recommended to choose freight logistics, which is more cost-effective. For smaller orders, it is generally more convenient to choose express delivery. Wholesale prices do not include the cost of goods shipping, and the shipping cost is paid by the buyer. The specific shipping cost is determined by the weight of the wholesale goods that day. The calculation of shipping cost is based on the total weight of the goods, not a fixed price for each item.
  
  Receiving and Inspection:
  Please inspect the goods before signing for them. To ensure the safety of the transportation, we carefully pack the goods before shipping. If there is a problem due to carelessness in not inspecting and signing for the goods, the buyer will bear the responsibility.

Please charge the battery.
