4. ResultsIn this section, the results of the different variables in the recorded language diary and the inferred relationship between the variables are presented to show the subject's use of languages ​​in different communicative situations in Hong Kong.4.1 Overview of language useIn the period of seven days, 83 interaction items were recorded with 114 main interlocutors involved (see Table 1). The largest number of interaction entries appeared on November 18 (Monday), and the fewest entries appeared on November 16 (Saturday). Although they lived in a Cantonese-dominant area, most interaction items (55, 65.5%) were made in pure Mandarin or mixed forms as the base language. Although not statistically predominant, English in its pure and mixed form as a basic language (10, 12%) is still in second place, followed by pure Cantonese (7, 8.4%) and the proper dialect mixed with some mandarin (1, 1.2%). Another category was also recorded: general mixture, in which several languages ​​were equally mixed. There are three types of codes mixed in the document, Mandarin and English (4, 4.8%), Mandarin and Cantonese (4, 4.8%), and Mandarin and its dialect (2, 2.4%). 4.2 Types of exchanges As Table 2 shows, the most frequently reported linguistic exchanges occurred between the subject and his classmates (38, 45.8%) and his roommates (18, 21.7%). Communication with staff members, including clerks, cashiers, and librarians, took up 19.3% (16), and 6% of the interaction items (5) were produced with the professor (and classmates).
