Hong Kong Hengfeng Bank Card cannot be frozen. The National People's Congress authorizes the Hong Kong Special Administrative Region to exercise a high degree of autonomy in accordance with the provisions of the Basic Law, and to enjoy administrative, legislative and independent judicial power, including the power of final adjudication, such as formulating monetary and financial policies on its own. If the mainland court needs to freeze the Hong Kong Evergrowing Bank Card, it needs to go through relevant legal procedures and assistance mechanisms. Therefore, mainland courts cannot freeze Hong Kong Hengfeng Bank Card.
