The colorful neon arch is located at the foot of Dongshan Mountain in Yuanbaoshan Park, which is the east gate of Yuanbaoshan Park. There is a huge colorful neon arch along the three-story and thirty-level stone steps. Especially at night, the lights on the arch are flashing and colorful, which makes people suspect that the rainbow fell from the sky. The slopes on both sides of the arch are full of green fields. Looking up from the arch, at the edge of the stone steps, there is a thick water gushing out from the mouth of the old faucet located halfway up the mountain, descending the mountain and merging into the circular pool in front of the arch, full of lingering charm.
