Well, day 4 was supposed to be easy – and ended up being the hardest! We were on the old bits of the wall with no walled bits up the sides and sand and trees down the centre. It was incredibly steep and the day was sweltering. This was the day they gave us magic boxes for lunch. This is a brilliant idea where you have your cooked rice and a sauce in separate sachets. Then you put a heat pack in the bottom of a plastic box, pour water over it and put the rice container above that with a lid on the bigger box. Stand the box on the sauce sachet. Mine was chicken and nuts. (Photo to follow) We also visited the Ming tombs, which were very interesting. We came off the Wall at about 5pm – the latest we have been all week!!
