I'm sorry for everyone this month, plus the replacement of monthly passes has to be suspended, not only at the end of the month, but also at the beginning of next month. Since mid-March, the home is being renovated, and my daughter-in-law goes to work, just I am an idler, so I have to go to the construction site every day to stare at it, take the time to sit on the construction site and code Braille, barely insist on constantly changing, and from time to time I have to accompany my daughter-in-law to go to the building materials city and electrical city, and I really can't save the manuscript.

It is expected to be completed in mid-April, and I strive to resume the update in May, thank you for your support and long live your understanding!! (To be continued.) )
