Three (revolutionary sacred) sites

There was, and still is, a widely recognized pantheon of revolutionary sacred sites in China. Always central and usually foregrounded was Tiananmen, directly below Mao's portrait as the fountainhead of authority.

Next in importance, and testifying to Mao's revolutionary legitimacy, were Jinggangshan and Yan'an flanking Tiananmen and located visually above (and historically antecedent) to the seat of power. Despite the consensus on their importance, there seems to have been no agreement as to their relative positions - did Jinggangshan stand to the left of Tiananmen or to the right?
