#20: N/A (Retired)
#21: If your mother can really pay for this trip, put her down for that. This needs to be reasonable. Like the pension she got every month and the saving history (not only the current month) can support her capability to purchase the round trip ticket and without causing any problems to her or your family's daily life.
I think they are more emphasized on the tie your mother has with China. Since she is retired, the tie get weaker. How can you show she has a strong tie is the point. But if they have prejudice then nothing will work. You have to go back often to see your mother and family.
