We need to develop critical thinking skills.

Critical thinking is thinking with a critical spirit, which is the opposite of blind obedience thinking.

Critical spirit is the unity of skeptical spirit, negative spirit and affirmative spirit.

Characteristics of critical thinking:

①Independence; not trusting others.

② Systematic; do not generalize.

③ Seek truth; do not flatter.

④ Reflective; not once and for all.

⑤Openness; not stubborn.
