How to write letters? ......

Wandering around,

Reward and punish unbelievers,

A letter,

Loyalty, honesty,

Detailed and credible,

That heart,

Credit cooperatives,

Postage postcards,

Friends are honest,

Traffic lights,

Without faith, people cannot stand,

Radio communication,

Keep your word, keep your word,

24 flowers,

Geographic information system,

Twenty-four rumors,

The second signal system,

The first signal system,

It is better to believe in books than not to have them.

Trust people, lose the gourd ladle,

Satellite communication earth station,

Twenty-four Hua Xinfeng,

Keep your word, keep your word,

Listening to both makes you clear, favoritism makes you dark.

Han Xin used his troops and did too much.

Letter conveys letter, doubt conveys doubt,

People without faith don't know what they can do.
