To my dear man

Hi dear. Today the weather in Guangzhou is very good and what [is] the weather [like] in your home?

I miss you.

===============================

The last bit "in your home" is a slight problem.

Are you asking what the weather is like in his dwelling ? I think that this is not the case.

If you both came from the same area, you would say "at home"
