一脉相承 | yī mài xiāng chéng
On July 7, Xi Jinping addressed the G20 in Hamburg, Germany. As a nod to China’s leadership from the previous meeting, Xi cleverly used this 成语 to frame this meeting as a direct descendent of the Hangzhou one. The themes of this speech were also similar to those expanded upon by Xi in Davos earlier this year.
MEANING
Be descended from, or from the same origin
ORIGINAL
