Hello Guofei, thank you for the kind message. I hope today's meeting goes well. I will be posting pictures here later.
About your question... I will answeer you in a private message.
Just an unrelated question: I notice that you work between Japanese and Portuguese, yet you are writing in English, and you are in China. How many languages do you speak? If you speak all these languages, how did you manage to do that?
