Biji Alley or Comb Lane - is located in the north bank of the canal with 150m length and 4m width, which is in the west of the city. The ancient Piling courier station had been established here since the fourteenth year of Emperor Zhengde's reign (1519) of the Ming Dynasty. The Comb Lane was originally called the "Flower Market Road". In ancient times, shops selling combs and bijis (biji is a kind of double- edged fine-toothed comb) were arranged in close rows, and most of the shops and workshops along the road were specialized in producing and selling combs. Hence, there was a proverb saying "as the rouges in Yangzhou and the flowers in Suzhou, Changzhou is the No.1 in comb products". When the Emperor Qianlong visited here during his travelling in South, he changed the name "Flower Market Road" to "Comb Lane" when seeing the great variety of comb shops, which has still been in use today. The oldest "Old Bu Hengshun Comb Shop" in the lane was opened in the Emperor Tianqi's reign of the Ming Dynasty. Its combs won multiple awards at home and abroad, and have been highly praised by foreign friends in numerous large-scale exhibitions, thus becoming best-selling souvenirs in domestic and overseas markets. The Palace Museum has still kept the Changzhou combs produced in the Qing Lane" Dynasty up to now

The alleyway includes numerous shops selling traditional Chinese combs, though after a while they start to look the same. There is a museum opposite the site though it is not in the alley itself. Overall, not a lot to see - small street with a handful of shops on the canal.
