It seems like you’re asking about the age limit for floating in China. According to Chinese regulations, men and women have different age limits:
For men:
- Boys aged 8-18 ( elementary school students) are not allowed to take inflatable tubes or rafts on rivers.
- Men older than 65 years old need a doctor’s certification before engaging in water activities.
For women:
- Girls under the age of 6 years old should have adult supervision when playing near water areas.
- Women who are pregnant, menstruating, or having their menstrual period (with some exceptions) cannot engage in floating or other water-based entertainment due to health concerns.
These rules and guidelines may vary depending on local regulations. Additionally, individual preferences and abilities can also impact what is possible for individuals of certain ages or genders.
