• Shareholders preferring hard copies may request printed versions by emailing ir@pin-dao.cn or marking the reply form. This preference remains valid for one year from the date the instruction is received.

• The reminder letter was issued under the authority of the board and signed by Chairman Mr Zhao Lin. All personal data collected will be handled in accordance with the Hong Kong Personal Data (Privacy) Ordinance.
