In modern and contemporary history, when were there only chains and no boards left on Luding Bridge?

Luding Bridge is located on the Dadu River in Luding County, and is a national key cultural relic protection unit. The bridge was built in 44 years of Qing Emperor Kangxi and completed in 45 years (176). Kangxi wrote the title "Luding Bridge" and set up a monument at the bridge head.

Luding Bridge is 13 meters long and 3 meters wide. Thirteen iron chains are fixed in the landing wells on both sides of the bridge, nine are used as bottom chains, and four are used as handrails on both sides. * * * There are 12,164 iron rings interlocked, and the whole bridge weighs more than 4 tons. The bridgehead on both sides of the strait is an ancient wooden structure with unique style and features, which is unique in China. Since the Qing Dynasty, this bridge has been an important passage and military key for Sichuan to enter Tibet. On May 29th, 1935, the Chinese Red Army of Workers and Peasants flew through here to capture Luding Bridge and made it famous at home and abroad.

On May 29th, 1935, when the Chinese Red Army of Workers and Peasants arrived here on the Long March, 22 warriors of the Red Army Corps, facing the tight fire blockade of the river by two enemy battalions, "flew over the Luding Bridge" here, opening the way for the Red Army to go north. Three days later, President Mao Zedong, Vice Chairman Zhou Enlai, Commander-in-Chief Zhu De and the Red Army's follow-up troops calmly walked across the Huding Bridge.

Chairman Zhu De wrote a couplet titled "The Long March still remembers the danger of Shanghai customs, and the three armed forces are far away to guard against imperial invasion", which left valuable inspiration for later generations.

after the founding of new China, the people's government built the exhibition hall of revolutionary cultural relics of Hudingqiao and the Red Army Monument of Ludingqiao in Huding, and also built the Red Army Building, which contains a large number of cultural relics of the Red Army, historical materials of the Soviet government, paintings, inscriptions of party and state leaders and famous people for visitors to see.

It's true that the Luding Bridge was robbed, but it's not as magical as the legend. Exaggerated description is also needed to render feelings. Brothers think that the whole so-called "Long March" is not a process of running for their lives, but they still talk about themselves as fantastic. History is indeed strange sometimes, and they regard it as a joke.
