⑥Given that invention plays such an essential role in our life, what can we do to cultivate this precious spirit? ⑦ For one thing, it is advisable for the social media and publicity department to vigorously inform the public of the importance of invention. ⑧ For another, the relevant authorities should set up favorable regulations to encourage invention. ⑨ For example, they can set up the practice of giving premiums or issuing patent certificate to inventors.
