The first paragraph: write about the psychology of resignation (of course, it is not necessarily true). You can write some polite sentences. For example, after much consideration, I intend to resign from my present job ... or, due to family changes, I intend to apply for resignation from my present job. So the whole first paragraph can be written like this:

Dear HR Manager:

Hello!

After careful consideration, I decided to resign from my present position in the company. ...

For example:

Resignation report of property consultant

Dear Manager xx:

Hello!

After my consideration and the actual situation of the company, I decided to apply for resignation from the company. When I submitted this resignation, my heart was very heavy. Now the development of the company needs everyone to do their best. Because of poor health and some personal reasons, I can't make corresponding contributions to the company, and I can't bear to sit in the company and do nothing now. I decided to resign on X, so I asked for permission to leave.

Facing the haze of real estate ice age, in order to save cost and manpower expenditure, I have to formally submit my resignation to Tiangong Real Estate with regret and sadness when the Spring Festival of 20 13 approaches.

Over the past six years, Tiangong Real Estate has given me a lot, especially from a layman in real estate to a professional in the industry. To this end, I will always be grateful to Tiangong Real Estate, and this feeling will always accompany my future life journey.
