Within China or abroad? In the U.S. the issue seems to be a bottleneck due to embassy/consulate closures while the pandemic is active.
Chinese friends of mine who are studying in America have been able to receive renewed passports and travel permits (for children) after persistent pestering (daily emails) of the Chinese consulate closest to them, but they needed to show that they had A) a definite need, and B) definite plans to travel to China.
I've been going to their shop occasionally (whenever I need a major repair/overhaul) since 10 years ago. To sum it up, they treat their customers' bikes like their own! Great care and attention to detail combined with professional skills equals a great bike shop.
