Dadu Blue Highway Introduction
Among cyclists, there is word of mouth about a blue highway in this area, which is regarded as a good training ground due to its challenging slopes. However, it is surprising that after night falls, the streetlights illuminate not with the usual yellow-white light, but instead with a shimmering blue-violet glow, casting two trails of fluorescent light along the way, resembling a string of sapphire necklaces, lighting up the return journey of travelers.
