💎Incentive System (Invitation / Ambassador / Task / Leaderboard)

Four major drivers

1. Invitation System: Recommend new users → rewards for both parties.

2. Health Ambassador：Those who have made outstanding contributions to the community will be granted ambassador status, enjoying exclusive badges and higher governance rights.

3. Mission System: Daily/weekly health tasks (such as "go to bed before 11 o'clock"), complete them to get rewards.

4. Rankings: Establish lists such as "Sleep Improvement Star" and "Contribution Master", providing dual incentives of honor and rewards.

result Form a dual cycle of "sense of honor + economic rewards" to promote user growth and community activity.
