TS received a sms, the sms sender's number is his frens number,
but it's actually a PRC lady who picked up his frens' lost
phone.
The sms tells TS to contact the phone owner(TS's fren) to collect
back the phone.
Because the sms was sent at 10pm, so it's too late to meet up, so
TS and the PRC lady met the next morning to collect the phone
back.
After TS get back the phone, he/she go to international plaza to
give it to the owner, and the owner treat him/her lunch at "amoy"
hawker center.
I think it's "jia min" instead of "ja min". There's no hanyupinyin
for "ja".
