From Mao's Travelling Mangoes: Food as Relic by Adam Yue Chau.
''On 5 August 1968, Mao received the Pakistani foreign minister Mian Arshad Hussain, who brought with him a basket of golden mangoes as gifts for the Chairman. Instead of eating the mangoes, Mao decided to give them to the Capital Worker and Peasant Mao Zedong Thought Propaganda Team … that had earlier been sent to the Qinghua University in Beijing to rein in the rival Red Guard gangs. Two days later, on 7 August, the People’s Daily, the official news organ of the Communist Party-state, carried a report on the mango gift that included the following extra-long headline in extra-large font:
‘The greatest concern, the greatest trust, the greatest support, the greatest encouragement; our great leader Chairman Mao’s heart is always linked with the hearts of the masses; Chairman Mao gave the precious gifts given by a foreign friend to the Capital Worker and Peasant Mao Zedong Thought Propaganda Team’.
Mao gave the mangoes to Wang Dongxing, who divided them up, distributing one mango each to a number of leading factories in Beijing, including Beijing Textile Factory, where I was then living. The workers at the factory held a huge ceremony, rich in the recitation of Mao’s words, to welcome the arrival of the mango, then sealed the fruit in wax, hoping to preserve it for posterity.
The mangoes became sacred relics, objects of veneration. The wax-covered fruit was placed on an altar in the factory auditorium, and workers lined up to file past it, solemnly bowing as they walked by. No one had thought to sterilize the mango before sealing it, however, and after a few days on display, it began to show signs of rot. The revolutionary committee of the factory retrieved the rotting mango, peeled it, then boiled the flesh in a huge pot of water. Mao again was greatly venerated, and the gift of the mango was lauded as evidence of the Chairman's deep concern for the workers."
Then everyone in the factory filed by and each worker drank a spoonful of the water in which the sacred mango had been boiled. After that, the revolutionary committee ordered a wax model of the original mango. The replica was duly made and placed on the altar to replace the real fruit, and workers continued to file by, their veneration for the sacred object in no apparent way diminished.''
