What is the world like in Qingdao? Do you know that?/You know what?

I think Qingdao Shang Tong Tianxia is a more formal network promotion company. Their network promotion resources are very rich, and they are mainly middle and high-end customers. Although the fee is high, the effect is still good, which is much more cost-effective than the network company in Beishangguang. It's a pleasure to cooperate with Qingdao and Shang Tong.
