 The lack of environment for speaking the language and the difficulty of learning it created not just a lack of interest, but even great disgust by some towards it.Efforts in the 21st century to promote Mandarin Chinese education in Chinese Filipino institutions and recent utilitarian trends, such as more Mandarin job opportunities, recent immigrants from China or Taiwan, summer education trips to China or Taiwan, encouragement of universities and schools by past presidents, and education exchange deals with China have spurred interest and potential for growth in the usage of Mandarin.Sometimes Chinese Filipinos also code-switch Mandarin together with other languages, such as English, Tagalog (or other Philippine languages), and Hokkien, as a form of pidgin language, just like Hokaglish or Singlish.
