The People's Daily, the Communist Party of China's (CPC) flagship newspaper, published an article swearing allegiance to Xi - who is also general secretary of the CPC Central Committee and the Central Military Commission (CMC) - and called on the people to grasp a historic opportunity facing China.
It is the first time that the daily has referred to 64- year-old Xi as "lingxiu".
The CPC identified Xi as the core of the party in 2016.
Lingxiu means "leader" with a positive political connotation and refers to highly revered state leaders.

"The word lingxiu means more than just a leader. It is often bestowed on a leader who enjoys the highest prestige, who is the most capable and who is widely recognised by the entire party," Su Wei, a professor at the Party School of the CPC Chongqing, told state-run Global Times.
Since he took power in 2013, Xi has emerged as the most powerful Chinese leader in recent times as he now heads the party, the military and the presidency, unlike his predecessor Hu Jintao, who only got the coveted post of head of the military two years after taking power.
Since then, all organs of the party have declared Xi as the topmost leader of the party setting aside the principle of collective party leadership that was followed in the last three decades.
Su said the emergence of a "lingxiu" is the symbol of a mature political party, adding that in the last five years Xi's achievements in various fields, especially the anti- corruption drive, have been widely acknowledged.
