Thanks tvfan on the Japanese board who took notes for Jiwoo's message.

Here is my translation:

I've been studing Japanese hard.
Today I would like to greet everybody in Japanese.
Athough Japanese is difficult, I hope I could be able to converse with all of you in Japanese some time.
Since I would try harder to present great acting skills from now on, please keep cheering me up.
I wish today's concert can become a nice memory.  I love all of you.

Re: Hu Ping(胡兵)
Hu Ping(胡兵) was invited to present a flower bouquet to Jiwoo.  I can't remember the whole message but he was very nice and sincere by offering his wish to Jiwoo for being more beautiful and successful.  Jiwoo was also as humble as usual by replying that I felt so honored to receive flowers from such a terrific guy.  She also mentioned that she was surprised to see Hu Ping being so tall.

My remarks:  I was so shocked to see Hu Ping there since no info has ever been disclosed in Jiwoo's fan sites.  Though I know that Hu is now trying to enter the Japanese market and everything is arranged by his Japanese agency, I still felt so happy to see that he went there to present flowers to her even with his superstar status in Mainland.
