Happy Lunar New Year! 恭喜發財，牛年大吉!

Seeing how infrequently I update this profile, I'd like to wish everyone a happy Nowruz (March equinox) for the 21st of March. Spring showers bring April flowers which may bloom until June, and before you know it, it will be summer and hopefully lockdown will be on its way out.
