I have permanent resident card

Dear Consular,

I have been living in China for the last 15 years and received my Permanent Resident Card on June 11, 2019 (My residency permit number is CAN330467120906). I returned to Canada in late June 2019 to take care of my father who had brain cancer. He passed away on December 12, 2019. I have been taking care of my mother since then and had my return flight to China booked for February 7, 2020, but due to the Pandemic, my flight was cancelled. I returned to China for 2 weeks in October, 2019 and wanted to return in February, but wanted to ensure the safety of the citizens of both countries by self-quarantine at home. I was told that in order to keep my status, I must spend 3 months per year in China to fulfill the requirements. I am afraid because of the pandemic that I may not be able to fulfill this requirement. Could you please use your expertise and understanding to direct me. I love China and do not wish to jeoparadize my residency.
