We could visit China before, we just needed a visa, like we do if we visit a lot of countries. We toured China in 2016 and our experience was different to Petra’s. We were able to visit a lot of sites on our own and weren’t bothered by the security forces. The Chinese, however, are not a pleasant people. We frequently saw them pointing and laughing at overweight foreigners and hassling people on the pretence of leaving English. On our trip on the Yangtze, foreigners were allowed in to the dining room early as it was buffet style, the captain told us that when the Chinese came in it was like a plague of locusts and they pushed and shoved, piling up plates with food which they never finished.
