The second suggestion, although your daily work life is monotonous, there are people you don't know in this monotonous circle. I learned in Baidu that I want to find opportunities to communicate with them more. Maybe they are not good at communication like you. Slowly, you will find many interesting people around you.
The third suggestion is to help others if you can. Answering questions for others and sharing experiences all belong to this category. When you provide valuable help to others, others will naturally build trust in you, and slowly you will receive many "good people cards". If you can continue to help more people, others will naturally be happy to associate with you. After a long time, the people you helped will also help you. But be careful not to be too utilitarian.
