Taken in the lock of the Three Gorges Dam in Yangtze River, China.
“Entering 3-level-lock” was in my itinerary of my Yangtze River Cruise.
“What in the world is the lock?” was my first response.
They were talking about the lock system in the Three Gorges Dam. I just have never heard of the word in English before. The Three Gorges Dam has 5-level locks. We went through it in the last night on the cruise. Simply, we went in, they close the door, lower the water, and entered the next room. And repeating for 5 times. We stayed up to watch this, and actually this was pretty cool. The water went down quickly and I watched it past 140m.
