This morning, I will go to Mazhai township to see my agricultural science and technology demonstration households. This work was launched by the National Agricultural Ministry and is implemented nationwide. I will instruct seven farmers in total. Three of them plant sweet potatoes, one of them plants sesame, one of them plants sweet potatoes seedlings, two of them plant pumpkin. My responsibility is to help them to solve the technical problems they encounter in the process of their planting. Of course, I don't know everything, but I know many channels to get information. I may not know the specific issues, but I can ask other specialists for help or find the solution on the internet. I have set up a WeChat group and will invite the farmers in. If there is any new policy to benefit farmers, I will be the first to let them know. If they have any difficulties planting, they can let me know in the group at any time. Of course, I will go to their place to meet them in person and go to their farmland to see their planting situation. I will teach them how to make the most of the China Agricultural Technology Extension App. This app is very powerful. Its content is very rich, including laws and regulations, market price, operative technology, agricultural classroom, network book store and so on. Although I am an agricultural science and technology person, this is the first time I have interacted with farmers in person, so I cherish this opportunity. I hope that through my joint efforts with the demonstration households, they will achieve the goals of increasing agricultural production and farmers' income.

I think you want to say "The library begins at ten o'clock" and "The museum begins at nine o'clock." In English the correct way to say this would be: The library opens at ten o'clock. The museum opens at nine o'clock.
