I Want Respect, Not Hardware

I Want Respect, Not Hardware Plot:

Lin Xiao, the owner of a hardware store, runs the shop with exquisite hardware craftsmanship and delicate design sense, but has long been labeled as "just a woman selling bulky hardware" by people around, with no one noticing her professional skills. One day, a difficult customer came to the shop, not only nitpicking product details, but also publicly mocking her as "a woman doing hardware is just a formality". Lin Xiao finally couldn't bear it anymore, showing her patented improved hardware design, exposing the customer's scheme of shoddy workmanship on the spot. With her hard-core strength, she reversed all prejudices and won everyone's respect and the customer's sincere apology.
