In Spanish, there are two copula verbs SER and ESTAR. Ser is equivalent to the be verb in English, and estar and ser both represent state or something, but ser represents human attributes, and estar is temporary.
Ser is used to indicate a permanent situation with no signs of change.
ej:
My name is Chico.
China soybean. I come from China.
2.estar means a temporary feature or state that won't last long.
ej:
Estella Cansado. He is very tired.
Let's go on holiday. I'm on vacation.
Third, the same adjective is used with ser and estar respectively, indicating different meanings.
ej:
Esto Delgado. (I've lost weight recently)
Soybean Delgado. (I am a thin man)
Estaguapa. (She is very beautiful now)
It's Guapa. (She was born beautiful)
Estaing Wilders, Las Manzanas. (Apple is not yet ripe)

ej:
Eres sorprendente。 You're amazing.
I love you. I'm surprised.
