Please answer the following question: Write a multi-choice question for the following article: Article: BEIJING, July 21-More and more parents in Shanghai have found that their children are forgetting how to use Shanghai dialect to express themselves, according to a report in the city's Jiefang Daily on July 11, and some have begun forcing them to speak it at home. Language experts say that the promotion of Putonghua, and the large number of non-Shanghainese setting down in the city have meant that the local dialect has lost its previous high social status, according to the report. They have urged that the dialect be protected alongside Putonghua (also known as Mandarin), the nation's common tongue that has been systematically promoted since new China was founded in 1949. In their opinion, dialects carry and preserve local culture . They say that a dialect is not only a linguistic tool. But is also like a person's "birthmark" and part of their local identity and feeling of belonging. They recommended that TV and radio stations set up channels and programs using dialects , and that schools offer selective courses in which the dialects are taught. The experts also suggested that dialect be protected while maintaining high standards of Putonghua and a multicultural environment in the city.
