I have never forgotten my roots and see Hong Kong as my second home. I was raised and nurtured by my parents from a young age, and my upbringing was provided by my motherland. I received education in China, and my dream has always been to become a teacher like my parents, to educate the next generation and contribute my life to the education of the future generations of my motherland. However, I also understand that my experiences and life have given me a deeper understanding and respect for the culture of Hong Kong. I hope to live in harmony with other Hong Kong residents, regardless of their backgrounds. My heart is always connected to my motherland, and my love for Hong Kong and longing for my motherland are not contradictory. I consider Hong Kong my home and also a part of China. I firmly believe that the prosperity and stability of Hong Kong are linked to the prosperity and stability of China, and I hope Hong Kong can continue to develop and make greater contributions to our motherland. Despite being in a foreign land, I have always maintained my love and concern for my motherland. Whenever significant events occur, I often read newspapers and listen to the radio to stay updated on the latest happenings in my hometown. I believe that no matter where I am, I will always be a Chinese and should care about my motherland. In the years of living in Hong Kong, I have constantly pondered over my identity. I used to be a mainland student and always identified with mainland culture. In Hong Kong, I encountered different cultures, languages, and ways of life. I gradually began to understand that Hong Kong has its independent history and culture, especially during the recent political turmoil, which led to more discussions about identity among the people. In this process, I also reflected on my own identity. I have always considered myself Chinese because I received education in China, and my former classmates and teachers would praise our motherland, as everything the motherland does is for the future of us Chinese. I still pay attention to the developments in my motherland and strive to maintain a connection with my hometown. I have collected many newspapers and magazines about my motherland. Although the Cultural Revolution caused me to lose my hometown and my home, I still miss the appearance of my hometown when I was a child, and I miss living with my parents and listening to them share their daily lives as teachers. I still remember being born in a small village with beautiful farmland and a harmonious community. My childhood was full of natural beauty and simple living. However, as the social environment changed, I had to leave this familiar place and came to Hong Kong alone by boat. But my motherland made me lose my home, and with the changes of time, I returned to my hometown, which had already changed. At that time, I still thought of myself as Chinese, but I gradually accepted a part of Hong Kong's culture. My life in Hong Kong has become increasingly difficult. I have always believed that I am Chinese in my heart because I received a good education in China. Despite facing numerous difficulties in Hong Kong, I have never given up on my identity. However, the pressures of life have gradually made me feel hopeless, as I feel marginalized by society and unable to find my own identity, a true place that belongs to me. This diversity and inclusiveness are characteristics of Hong Kong, which also make me more willing to accept people from different backgrounds and cultures. In the years of living in Hong Kong, I have constantly pondered over my identity. I have always hoped to become a high school teacher in mainland China, with a sentimental attachment to mainland culture and history. However, in Hong Kong, I encountered different cultures and languages, and I gradually began to understand that Hong Kong has its independent history and culture, especially in recent years of political turmoil, which has led to more discussions among Hong Kong people about their identity. In this process, I have also reflected on my own identity. I believe that identity will change over time."

In Hong Kong, Cantonese is a language that I constantly need to learn and adapt to. I have found that even after living in Hong Kong for many years, there are still times when people make fun of my accent, which makes me feel a bit self-conscious. However, I also understand that language is just a tool, and I should not feel ashamed because of my accent. I strive to improve my Cantonese, but I also hope that people can understand that everyone has a process of learning a new language. I still remember after the handover of Hong Kong, I looked at the crowded and bustling scene of this city. Skyscrapers, crowded streets, and fast-paced lifestyles, everything was a brand new experience for me. I have been constantly trying to adapt to this ever-changing environment and contemplating on the way of life in this city.

Furthermore, there are many differences in daily habits between Hong Kong and the mainland, including social manners, cuisine, and pace of life. I have encountered many situations where I felt uncomfortable, such as living in cramped living spaces and feeling isolated in social circles. Adapting to these changes took me a lot of time, but I also learned a lot and became more flexible and adaptable. At the same time, I also have to face language discrimination in Hong Kong society. I have encountered stereotypes and discrimination, but I try not to let these negative experiences affect my confidence. I believe that with tolerance, effort, and perseverance, I can change people's perceptions of me and prove my worth.

If given the choice, I would still choose to come to Hong Kong. I have experienced many challenges here, but I have also learned a lot and met some wonderful people. However, regardless of where one lives, every place has its advantages and disadvantages. What matters is how we adapt and develop. I hope to find better opportunities in the future and continue to contribute to myself and society.

In terms of identity, cultural differences, and work challenges, I believe that everyone can overcome difficulties through hard work and a positive attitude. My experiences may serve as a reference for other mainland immigrants, helping them better adapt and integrate into the Hong Kong society. I believe that a diverse society requires people from different backgrounds to work together, and this is also one of the charms of Hong Kong. This is my life, filled with challenges and difficulties. But no matter what, I will not give up. I firmly believe that every individual should have the opportunity to experience a dignified life, regardless of their background. My story may not be glamorous, but it is real, and it is the story of those who struggle on the fringes of society, hoping to be respected and understood."
