I’m slacking off quite a bit lately. Not making the progress I hope for from day to day.
Still, an postcard arrives to encourage me…

The beginning of the accompanying email tells me…
In ancient times, Yulin used to be the northernmost border of China. Various walls were built throughout the centuries with the earliest dating to the 5th century BC right up to the 15th century AD, covering the rule of several dynasties. Some preserved walls and forts can still be found in Yulin and nearby cities but the most significant is Zhenbeitai Tower, the largest watchtower on the Great Wall.
Too much commuting has done me in, I think. That one whole day in the office (more like, the 5 hours of round-trip commute time did me in)
Tomorrow’s another day. Or so I hear.
