I think when your mother can hear your voice on the phone, she will be so excited. You can call her at least twice a month. It will make her extremely happy.
After watching these three series: 90 to 92, I was touched with the way Mother is dealing with her difficulties and problems. I am a Chinese living in Canada, who once lived in Fukuoka, Kyushu, Japan for three years. I have been to Kumamoto Prefecture many times. It is a beautiful place. I hope everything goes well for Mother and Daughter.
It's a heart-broken moment to watch the girl crying. She just didn't want to hurt the feeling of any adults. By doing so, she must have had swallowed much pain than we can imagine. Wish the mother and daughter live well no matter in Dalian China or in Japan.
Such great mom and daughter! ‘ why I live here’? As a Buddhism practitioner, I believe everything happens for a reason, we planted seeds before and harvest the fruits later on , we might have created certain connection with that place in previous life, we called that as 缘, ( Yuan, a doomed destiny), so we travelled from far away to there this life. I appreciate that a single Japanese mom put so much effort to make a living and raise her young daughter in China. Wish her best luck!
