It is Day 4 in China, today.

I arrived  at Shanghai, China Last Monday, I first went to Shanghai office.

Then I discuss with my co-worker about this business trip's schedule.

After that, I went to take a dinner with some co-worker.

First restruant is japanese izakaya, then we moved to Bar, 3rd place is ...

Next day, Day2, I was little bit hand over, but I had to move to other city.

I went to other by co-worker's car, but I was sleep almost time..

After that, I went to customer site.

Day 3, I moved to other city again.

I arrieve the city Wedesday, I will stay at this city until Friday, then I will go back shanghai Friday afternoon.

Something that I thought in this 4 days is the I do not use English than I thought.

I basically work with my co-worker. He can speak Japanese. Of cource his Japanese is not perfect, so I sometimes use English to complement his Japanese, but I basically do not need to use English. 

Something that is necessary in China is Chinese.

If I am alone, I can not enter to customer site. I can not order and pay lunch. Especially, in local area.

Talking Chinese is important to live in China.

I will keep practicing English and also I will try to learn Chinese.
