am i allowed to apply for two conescutive 144h visa

Hello, I am travelling from Bremen (Germany) via Amsterdam to Shanghai (PVG). From Shanghai I will go the next day to Taipei (Taiwan). I will stay there for seven days and return to Shanghai and three days later to Germany, again via Amsterdam. Is it possible to apply twice within this short time for 144h twov? or do I need to apply for a 30 days entry permit with double entry? Thanks!
