For the former it would be impossible unless all the financial institutions were willing to cooperate. For the latter, even the Ministry of the Interior, in charge of land policy, can't find out who all the land in the country belongs to, so it would be even more unlike ly for us to find out.
前者除非是各金融機構願意配合；後者連掌管土地的內政部目前都做不到全國土地總歸戶，我們要查證就更困難了。
