Players need to unlock Suzhou House first, and then go to the upper right position of Suzhou House. You can see a signboard that says "Longan Square", and you can see the wishing tree if you go further from Longan Square.
Wishing is a task in the original god game, which requires players to go to different places to find clues and complete a series of challenges. After completing the task, players can get rewards in the game, including experience value, gold coins, props and so on.
