Dadu Blue Highway

Among cyclists, there's a 'Blue Highway' passed down by word of mouth. It's considered an excellent training ground due to its challenging uphill climbs. However, little did one expect that when the streetlights illuminate after dark, they aren't the common yellow or white lights. Instead, they are a series of luminous, blue-purple cool lights, scattered along the way like two fluorescent ribbons, resembling a string of sapphire necklaces that light up the traveler's path home.
