In 2011, the precision instruments was already affected by a smaller area reconstruction's vibration,[4] and because Line 16 would only be 200 meters away from Peking University, the precision instruments would be severely affected by the line, and scientific work would be severely disrupted.

Because of this, the Beijing Municipal Planning Commission studied the vibrational impact of the campus precision instruments,[5] and NPC deputies submitted a proposal in 2012.

On August 5, 2013, the Beijing Municipal Planning Commission announced a proposal for rerouting Line 16 between Xiyuan and Suzhoujie stations.

[6] Previous studies has shown that the line cannot meet Peking University's vibration and noise reduction measures.

[7] In December 2013, the final plan was released, which included Wanquanheqiao station.
