The next day, the two of them have to go to the old lady's house to thank her for all she has done for them. The next morning, they sit down to work on their research proposal. The first part of the proposal is the planning of a cultural corridor leading to a multi-point connection. The second part is the plan for the historical park of the Baifuquan. The third part is a master plan to expand the green space of the river. The master plan should focus on the architectural style, heritage preservation, and management of the environment. The rain is forecast for the following day, so they'll have to wait until then.
