The question is how do we answer the questions:
We want to be fully flexible - want it for 10 years - do we state that we want it for 10 years, do should we say that we want it for the validity period of the passport?
Maximal length of stay - I doubt I will ever need to stay more than 2 weeks - should I put 4 weeks.
Obviously, I should say multiple?
This would be our first Chinese visa application?
