There is a red heart when harvesting crops in the national farm game. What is the heart for?

This is the "Valentine's Day" activity of the game update.

From February 5 to February 12, the harvested agricultural products have a certain chance of getting love, and 2 14 pieces of love can be exchanged for decoration "red roses".

Click on the "Red Circus" across the river-festival exchange, to see the details of the activities and the love you have gained so far.

PS: decorations can only be received once.
