How to use these IDs in the console

In Steam, add -debug_mode to the game's launch options (Properties → General).
In the game, open the console with the ` key (§, ~ or ^ on some keyboards).
Paste the command (give_title h_china) and press Enter. Using the console turns achievements off for that game.
