Following each Hunger Games, the Capitol runs a Victory Tour that features the victor (or victors) of the previous Games traveling around Panem. Designed to lower the districts' self-esteem and show off the power the Capitol has over them, the Tour is placed almost halfway between the annual Games in order to "keep the horror fresh and immediate". It begins in District 12 and then goes in descending order to District 1, followed by the Capitol. The winner's district is skipped and saved for last.
As a general rule, all the districts are supposed to act happy and cheer on the victor, although many of them are very bitter and angry at the loss of their loved ones.
Generally, those who go on the Tour are the respective victor and his or her mentor, escort, prep team, and stylist. Like the Games, the tour is televised. The tour was very hard for the 74th Hunger Games winner, Katniss Everdeen to go through since she saw the family and friends of the tributes killed in the arena, some of them by her own hands.
The victor(s) give(s) a speech in each district. The speech is about their victory, but in Katniss and Peeta's case, they are the beginning of the uprising. In District 11, Katniss gives an additional speech on Thresh and Rue.
The Capitol appearance is supposed to be a huge dinner with dancing and throwing up your dinner to eat more food. The Capitol appearance is supposed to be the grandest of all the celebrations in the Victory Tour. In Katniss and Peeta's Capitol appearance, Plutarch Heavensbee gives Katniss a small clue about the Quarter Quell's arena by showing her his watch that briefly flashes a picture of her mockingjay pin.
Capitol appearances kick off with a televised interview with the victor(s), conducted by Caeser Flickerman.
After the interview, the victor and his/her team are treated to an expensive ball-style dinner at President Snow's Mansion.
Once the tour reaches the victor's home district, a massive dinner is held on the last day of the Harvest Festival, which all of the district's residents attend. In the poorer districts, it's a much-needed chance for people to fill their stomachs.
