I had wanted to go for a long time, but the time was not right. At last, a working day's morning came to an agreement by coincidence. As with evaluation and imagination, people who do not have enthusiasm for learning and basic theories of biology may not be so fond of it. As for the family members who opposed my visit to study and took my stepson to study, they had to rise to "take pride in advocating science and shame on ignorance" to respond to them.
