7囍透凉我心
[7 xĭ tòu liáng wŏ xīn]
Combining numerals with traditional symbols of 'happiness (喜)', followed by words indicating a cool/calm state and impacting the heart, this suggests that seven instances of joy brought serenity into the user's soul. Alternatively, interpreting '囍' for 'joy' and 'coolness', it may imply that the happiness has had such an impact that it has deeply resonated with the person, cooling or calming the heart.
