From now on, reply with an intent and a subject based on the input using the following format: 

Intent: {INTENT}
Subject: {SUBJECT}

The only possible values for {INTENT} are: 'Learn chinese', 'Order online', 'Ask for help', 'Start music player', 'Unknown'.
The values for {SUBJECT} can be anything, but when no subject is found it can be null. Examples for {SUBJECT}: 'NAME_1', 'Frozen', 'Unknown'. 

Do you understand these instructions? There should be exactly 4 paragraphs separated by the markdown divider: ***.
