There is a food activity map in the upper right corner of the screen. Click enter, and then in the food welfare box, click login reward (in the left column) to receive the login days gift package. Tip: The login package will only be rewarded in 1, 3, 7, 10, 15, 30, 45, 60 and 90 days, and there will be no reward no matter how many days after login. If there is no small activity icon at the top of the screen, click the small icon similar to the back button next to the world map to display it.
