12-Apr-2003 -- I went for this confluence twice.
First time is 6 April 2003. I couldn't find a detailed map of the area of the confluence, I only knew that it's in Chang'an Town. I began my tour 10 km away from the confluence, at first I took a motocycle, but later I found that the confluence is in the mountains, so I began to hike following a path. It was a rainy day, the ground was very muddy, but the scenery was very beautiful. After 3 hours' walk, I gave up because the time was late, I had to go back or else I couldn't catch the bus.
A week later, I went for it again. I took a bus to Taiyigong where I left last week. Walked south following the road to Cuihua Mountain. I found the confluence is on a hill just beside the gate of Cuihua Mountain Park. The hill is 330 meters high. To my surprise, the confluence is very near the peak, only 30 m away from it, and it's 12 meters off the path. Though I got lost on the hillside, arriving to the confluence was not very difficult.
Here is the detail I wrote in Simplified Chinese.
