History and background of footbinding in Taiwan

Here's the less interesting part, very general as well and only focused on Taiwan.

Footbinding was a custom passed down from approximately a thousand years ago, though no one really knows the exact time period of when it started: the earliest speculated date is 221 BC - 206 BC, the Qin dynasty. The custom is popular mainly with the Chinese ethnic of Han, though not all cultural groups practiced such a custom (For example we based on the household registration data during the Japanese Colonial period that the Hakka did not hold such practice.). At first, the practice was mainly popular with the wealth royalties, as women were unable to move around and perform laborious work. However, this fashion trend slowly spread to even the poor and by the Ming dynasty (1368-1644), as long as it was economically possible, every household with a daughter would bind the daughter’s feet.

During the Qin dynasty, when the Manchurians took over China in 1644, the regime attempted to ban the practice of footbinding and did not allow their own people to begin such practice. Nevertheless, even the Manchurian laypeople, who had never held such practice, became absorbed in this fashion trend of binding the feet, allowing the practice to continue with the Han people for another 100 years, even though, for the most part, they never practiced themselves.
During this time, many women can to Taiwan from China, which not only popularized the custom of footbinding, but it became a mark of status. Nevertheless, in 1895, when Taiwan became under Japanese rule, footbinding came to be seen by the Japanese as a part of the Three Bad Habits (among opium and wearing of the queue) that needed to be eliminated. At the start, there was no official ban issued on footbinding, but the practice was merely advertised as a bad habit through education and the media in order to encourage the women to unbind their feet. For example, a report by the Japanese on a typhoon that hit Taipei On August 6, 1898, which caused a flood and 1390 houses to collapse, stated that of the 85 deaths that were caused by the typhoon, most were women with bounded feet. Many of the educated were the first to begin the anti-footbinding movement. In March, 1900, the first Natural Feet Society was established in Taipei, thereafter many branches of the Society was established in other parts of the province, among with other organizations with similar purpose. However, the custom was not so easily abolished and took until 1915 before an official ban was issued by the Japanese government to stop the practice. During the beginning of the anti-footbinding movement, most of the founders and members of the organizations were men who assured that all the women in their family have unbound their feet.

In 1911, an organization named Taipei Society for Unbinding Feet was established whose members were only women. At the time, it was believed that this type of organizations, originated by uppe rclass women, were the reason why footbinding became elminated so quickly soon after, as the Office of the Governor-General decided in a meeting in 1915 to completely abolish this practice and issued a ban at the beginning of the year. By August, there were approximately 763 000 women who have unbounded their feet, and was continuing to increase annually.

Why was it so difficult to convince the Taiwanese society to stop this custom when women were clearly subjugated to excruciating pain with injuries that hinders their movement for the rest of their lives?
