Thanks. I hope that we can drink beer in Viet Nam when you come back here. I only posted some posts in Facebook, Twitter, Linked In, etc. I haven't spend any money for advertising because we are living in covid-19 pandemic. I am an value investor also so I always want to minimize risks as much as possible. We think and invest for long term. Honestly, we were quite lucky because covid-19 helped our QR Code attendance get tractions very quickly. We keep our jobs so we have money to raise our children and family so we don't need short term thinking for our apps.
