In recent years, people are beginning to use home robots in their daily lives. Thanks to modern technology, these smart machines can perform many household tasks automatically. Although home robots bring many benefits, they also have certain drawbacks that users should consider.

Using home robots has several advantages. First of all, they help save time and effort. For example, robot vacuum cleaners can clean the floor while people are working or relaxing. In addition, some robots can cook simple meals, water plants, or even take care of elderly family members. This makes life more convenient, especially for busy families. Moreover, home robots can reduce stress because people do not have to worry too much about housework.

However, there are some disadvantages to owning home robots. One major problem is the high cost. Many robots are expensive to buy and maintain. Another disadvantage is the risk of technical problems. If a robot breaks down, it may stop working suddenly and cause inconvenience. Furthermore, people might become too dependent on robots and become less active.

In conclusion, home robots may make lives easier and happier, but there are certain problems as well. Therefore, we should use them wisely.

The line graph shows population trends in Viet Nam from 1960 to 2020, focusing on the percentage of urban and rural residents. Overall, the urban population rose steadily throughout the period, while the rural population declined.

In 1960, most Vietnamese people lived in rural areas, which accounted for 85% of the total population, compared to only 15% for urban areas. However, from 1960 to 1980, the rural percentage saw a slight drop to 81%, and urban dwellers increased to 19%

By contrast, the urban population rose throughout the same period. From 1990, the decline in the rural population became more significant, dropping from 80% to 70% in 2010, and finally to 63% in 2020. Simultaneously, the urban percentage nearly doubled from 19% in 1980 to 37% in 2020. The gap between the two percentages narrowed consistently over the 60-year period.
