yes China, has rules that are often enforced differently to how it is written e.g. even china cits government travel agencies run trips to tibet , but if you write places you will visit in tibet on your visa application then you won't get your visa, and the media in china will talk about tourism in tibet autonomous region including the number of foreigners going there , so who knows how they were meant to get their visas if they can not write the words on their visa application,...the anomaly is however if you write other cities in china and even if you presented an ongoing ticket on arrival to exit to nepal they will not worry about it.
