Is the weather in Dalian cold on September 21, 2011? I'm waiting online, I need it before the morning.

It’s not cold, don’t worry, a long-sleeved shirt will do. The pants are still single and it's not cold.

But it’s a little cold at night. . . Today it is 23-16 degrees, tomorrow it is 24-15 degrees, and the day after tomorrow will be about the same. The weather in Dalian will last until October 1.

I hope you are satisfied with my answer.
