A big white horse rode to the door to give nucleic acid reagents to the elderly in Changchun, which attracted attention. However, the reason why this Dabai worker chose to send nucleic acid reagents by horse riding was mainly because these old people were able to take some trails when riding in the countryside, which greatly shortened the time for sending nucleic acid reagents.

1. Riding in the countryside will be more flexible

A Dabai worker in Changchun did not choose some developed means of transportation to send nucleic acid reagents to the elderly in the village, but chose to ride horses to send nucleic acid reagents to the elderly living in the village. Part of the reason is that most of these elderly people live in rural areas, and the roads in rural areas are not as extensive as those in cities. In this case, riding a horse can better adapt to rural traffic. After all, riding a horse is more flexible and convenient than walking and using other means of transportation. Because in the countryside, there are many roads that are difficult to walk, and sometimes it may not be possible to get there by car, so driving is likely to be particularly inconvenient. After all, there are all kinds of roads in rural areas, and it is very likely that there are some roads that cannot be crossed by any means of transportation at all. Second, riding a horse can greatly shorten the time of sending nucleic acid reagents < P > Secondly, besides being flexible, there is another particularly important reason that local people can choose multiple routes by riding a horse. They can choose to ride some small roads, which can greatly shorten the distance and improve the efficiency of sending nucleic acid reagents. But this method is only limited to those who are particularly familiar with the roads in rural areas and cities. Because ordinary people are not familiar with the path at all, they are likely to get lost by taking the path, but they will waste a lot of time on the road. III. Conclusion < P > Generally speaking, this Dabai staff member chose to ride a horse to send nucleic acid reagents to the elderly in the village for convenience and speed. After all, the delivery of nucleic acid reagents itself is also efficient. So this one Dabai chose the quickest way.
