Can I still go after being rejected by Hong Kong for 19 years and 23 years?

yes. China and Hong Kong's refusal to enter the country can be lifted in one to three years. After being refused entry in China and Hong Kong in 19 years, they can enter the country in 22 years and can go in 23 years. Hong Kong, China, referred to as "Hong Kong" for short, is the full name of the Hong Kong Special Administrative Region of the People's Republic of China.
