The sign of hope is to kiss your three middle fingers and then raise it.
Katniss Everdeen is from district 12, which is the coal mining district.
The Seam, where Katniss and her family live.
Katniss lives in district 12. She lives in the poorest part called the Seam.
I believe they were saluting her bravery, or they were perhaps showing that they have hope for her.
They live in the country of Panem, in District 12.
district 12
There is no District 12...
District 12 then she moves to the victors villiage in district 12 when she wins The Hunger Games
Prim is a young girl from district 12, the coal district. She greatly loves Katniss and wishes for Katniss to always to be safe!
Peeta and Katniss live in District 12, in the Seam neighbourhood.
I believe that you are talking about when, in the Hunger Games, she covers Rue in flowers to defy the Capitol, and holds two fingers to her mouth, and extends her arm out towards a camera she saw. (She knew where a camera was, and wanted to show her friends and family at DIstrict 12 that she was OK) It is a sign they used at District 12. She has this respect because everyone knows her as the girl that hunts for food for their district. Some of what Katniss catches in the Wilderness is traded to Greasy Sae and other people who live in the town for money. She also stepped up to take her sister's place at the reaping, which was honorable. In other words, everyone in District 12 respects Katniss Everdeen. I hope that helped :D
Peeta comes from district 12 with Katniss.
