can the visia be used twice on a return trip (europe-china-japan, and japan-china-europe)

Can I enjoy the 144hr twov on both legs of my return trip. Going France to Shanghai to Tokyo, i can stay 144 hr in Shanghai, then coming back one week later from Japan to Paris by Beijing, can I apply again for the 144 hr twov in Beijing so globaly I'll stay 2x6 days in China in a month time
