What's the difference between a tourist line and a ground connection?

Grounding and dedicated lines are the same in operation! ! They all receive guests and then hand them over to local operators. The difference is the special line, which is generally a delegation from different places, and the ground delegation is generally a local delegation. They all hand over the guests to others for operation, but the special line is for example, I take away the guests from Yunnan in Chengdu, and I take away the guests from Yunnan in Chengdu. Hello, I received the guests who came to Chengdu to play in Chengdu!

Also, in many cases, they exchange customers with each other. I do Yunnan special line in Chengdu, and give the guests to Yunnan to pick them up. Yunnan successfully received the guests who came to Chengdu and gave them to Chengdu Special Line! !
