please help me write a literature review of Previous research on language attitude in China

Language attitude refers to an individual's feelings, beliefs, and opinions about a particular language or languages. In China, language attitude has been a topic of interest for many researchers, given the linguistic and cultural diversity in the country. This literature review provides an overview of previous research on language attitude in China.

One of the earliest studies on language attitude in China was conducted by Lambert and colleagues (1958), who examined the attitudes of Chinese students towards English and French. They found that the students had a more positive attitude towards English than French, which they attributed to the higher status of English as a global language.

In a more recent study, Li and colleagues (2019) investigated the language attitudes of Chinese university students towards English and Mandarin Chinese. They found that the students had a more positive attitude towards English, which they attributed to its perceived usefulness for international communication and career development.

Another study by Yang and Zhang (2016) examined the language attitudes of Chinese speakers towards Mandarin Chinese and regional dialects. They found that while most participants had a positive attitude towards Mandarin Chinese, they also had a strong attachment to their regional dialects, which they viewed as an important aspect of their cultural identity.

In a study focused on minority languages in China, Hu and Li (2018) investigated the language attitudes of Tibetan and Mongolian students towards their respective languages and Mandarin Chinese. They found that the students had a positive attitude towards their native language, but also recognized the importance of learning Mandarin Chinese for educational and career opportunities.

Finally, a study by Peng and colleagues (2015) examined the language attitudes of Chinese students towards English and Japanese. They found that while students had a generally positive attitude towards both languages, they viewed English as more important for their future careers and international communication.

Overall, previous research on language attitude in China has highlighted the complex interplay between language, culture, and identity. While English and Mandarin Chinese are often viewed as more prestigious languages, regional dialects and minority languages are also valued as important aspects of cultural heritage. Understanding language attitudes in China is therefore crucial for promoting linguistic diversity and cultural understanding
