When is the best time to send a blessing message on Lantern Festival ~ early morning or evening?

The best time should be directly at night, because most people have no rest at night and are doing what we like, so most people will receive your message at this time.

As long as many people receive your news, they will have a particularly good impression on you, or think that you are a particularly warm person, so that they can achieve their goal of caring for others.

You'd better not choose the early morning, because most people have already gone to bed in the early morning, so you won't see the news for sure. Evening is the most suitable time.
