Can you continue to get the dividend of domestic rural joint-stock system after emigrating abroad? My rural hukou village has implemented the villagers' shareholding system.

Yes, if you have dual nationality, you can get dividends from the domestic rural joint-stock system according to the current situation. If you don't retain your nationality, it is unacceptable to do so in a conservative way.

Dual nationality means that a person acquires the nationality of country A through procedures and acquires the nationality of that country again in country B. In public international law, nationality is the basis for a natural person to have a loyal obligation to a country and for the country of nationality to exercise diplomatic protection. People with multiple nationalities may have loyalty obligations to many countries and enjoy corresponding rights, so they can continue to enjoy the rights and interests of domestic rural dividends.
