This is because the notary office in China usually only works on weekdays, and is generally closed on weekends and legal holidays. If notarization service is needed, it is suggested to inquire about the opening hours of the notary office in advance and arrange the time reasonably.
If you need urgent notarization service, you can consider contacting other local notary offices or professional notarization services. At the same time, electronic notarization can also be considered, which can be carried out anytime and anywhere, with higher convenience and flexibility.
