According to my knowledge, in China’s nightclubs (夜场), some venues may offer discounted tickets or special promotions for seniors aged 65 and above. However, it depends on the specific nightclub and their policies.
Typically, these discounts are offered to encourage more elderly people to visit the club and enjoy themselves. Some clubs might have a “senior’s night” event where they offer lower prices or special activities specifically designed for seniors.
It would be best to check with each individual nightclub directly to find out if they offer any senior discounts (65+) on May 20th (520) nights, as every club may have its own rules and promotions.
