Both market towns have become part of the Tai Po New Town in the late 1970s and early 1980s. In present-day, Tai Po may refer to the area around the original market towns (i.e. Tai Po proper), the new town, or the entire Tai Po District.
There is a story that Tai Po was originally called Tai Po (大步), lit. big step. Once upon a time the area was a big forest. When people wanted to pass through the forest, they would walk faster with big steps for their fear of the forest. Some say there were tigers around, so people walked with big steps to avoid being eaten.
