On the evening of December 18, many residents of Lanzhou, Gansu reported that when they purchased the Lanzhou Rail Transit electronic metered ticket at the original price of 300 yuan, the payment amount was abnormal. Some had changed to 30,000 yuan, and some users even paid 3 million yuan. In the early morning of December 19, Lanzhou Rail Transit issued an apology letter about the abnormal payment, stating that during the issuance process of the electronic counter ticket, the system repeatedly converted the amount due to network stuttering, and the fare amount was inconsistent with the displayed amount, and there was an abnormal payment link. Passengers who have already paid abnormal ticket amounts have been refunded in full and given a 100-time Lanzhou Rail Transit electronic ticket card.
