Auspicious train tickets^[1] (Chinese: 吉祥語車票; pinyin: Jíxiángyǔ Chēpiào) refer to train tickets with auspicious messages on them derived from the beginning and end stations on the ticket. Messages often employ homophonic puns in both Mandarin and Hokkien and shuffling the order of characters to reach the desired effect. In Taiwan, the Edmondson tickets are sought by collectors and people wishing for good luck.^[1][2]

In 1973, an NHK television show in Obihiro, Hokkaido, Japan reported that tickets from Kōfuku Station and Aikoku Station carried an auspicious meaning. The kanji of the two characters could be interpreted as "happiness" and "country of love", respectively. The two stations then saw a surge of tourists seeking the tickets.^[3][4]

In 1993, after preservation work was completed at Bao'an railway station, the Taiwan Railways Administration (TRA) sought to promote the historic station for tourism. Railway researcher Ming-xun Hsieh (Chinese: 謝明勳) proposed that the TRA sell special edition tickets from Yongkang railway station. Hsieh was inspired by the Kōfuku–Aikoku ticket's success in attracting visitors and believed the same strategy would work in Taiwan as well.^[2] The ticket's characters, when read in a clockwise fashion, read "Yongbao Ankang" (永保安康), which meant "peace and health forever."^[1] The ticket became an unexpected hit and started the practice of collecting auspicious train tickets.^[2]

The Yongbao Ankang tickets saw a surge of popularity on 9 September 2010. Tickets in Taiwan are printed with the date and time when entering the station. Since the year 2010 is year 99 on the Minguo calendar, the printed "99-09-09" was seen as especially auspicious since nine (九) is pronounced the same way as (久; jiǔ; kiú), the character for "long time". The limited edition tickets, which were printed on thicker paper, sold out very quickly.^[5]
