What do you mean by touching the strings?

What makes you a little sad, what makes your heart suddenly tense, what makes you nervous, what makes you like it, and so on. It is the feeling of that moment.

Touching the heartstrings (selected by Chu Dong) and making sentences:

What is kinship? She is instantly touched by her heart, but it is often a complete change. It is the power that can change the expectation for ten months, the magic that can forget the mission, and the eternal longing for peace.

Affection is an instant inner touch; Affection is a permanent contribution; Affection is a kind of depth; Affection is a kind of sunshine bath that is unconditional and unrequited.

Honesty is gold, which can touch the most sensitive nerve in people's hearts and light a heart lamp that never sleeps.

A true friend will hold your hand and touch your heart.
