Walking along the Yellow River, we watched the moon climbing higher and higher.
We also watch the sun going down. The sky, the mountains, the river, they keep changing their colours every minute.
Finally, we went down to the banks of the Yellow River, to pick some rocks as a memento of our visit to the Yellow River. By then, it was almost pitch black. On the way back, I actually stepped into the mud, and made a mess. My friends pulled me out of the mud, helped me to clean up enough to walk back to the hotel. The temperature was below freezing at the time, and the sun has gone down. Fortunately I had a spare pair of dry socks with me. Otherwise it would have been unbearable.
The Yellow River has nurtured the Chinese civilization for thousands of years. In turn, we have changed it, but not necessarily for the better. I have seen how it got yellower and muddier as it flowed downstream, because of the reddish-yellow mud that got washed into the river.
I learned that NorthWest China was not as dry and devoid of grassland and trees as it is now. In fact, for two thousand years the region has seen the rise and decline of quite a few kingdoms, some of which seriously threatened the Han-majority dynasties. It is partly due to the cutting down of trees for agriculture and other reasons that worsen the soil erosion, which worsen the drying of the land, which in turn worsen the soil erosion, ...
Now the land is poor, the people are poor, ..., and the living is hard.
We contemplate the situation of the people living there for quite a while. In the end we sang and pray for them, before we went back.
