Lin Yun thought it was excellent, and its effects were comparable to modern soaps. She only asked Wang Xifeng to make further improvements to the shape and packaging.

Wang Xifeng felt reassured after receiving the Empress's approval.

She examined the soap samples repeatedly, pondering how to improve them, from the shape to the packaging.

On this day, she specially set up a banquet in her courtyard, inviting the sisters in the mansion to come and taste the food, and to help her with her plans.

Tan Chun arrived first, dressed in a light green dress, her steps light and graceful.

Upon entering, she noticed several bars of soap of various shapes on the table and her eyes lit up: "Sister Feng, are these your newly made soaps? They're so beautiful."

Wang Xifeng smiled and pulled her to sit down: "That's right! Her Majesty said I should improve it a bit more. I've thought about it a lot, and all the sisters in our household are clever and skillful, so they can definitely help me come up with a good idea."

Just then, Yingchun and Xichun arrived hand in hand.

Yingchun, being gentle by nature, picked up a bar of soap and examined it closely. She said softly, "If this soap were carved into the shape of a flower and given a delicate fragrance, it would surely be even more appealing to young ladies."

Xichun was the youngest, but the most ingenious. She picked up a square bar of soap and suggested, "Why not press some auspicious patterns or short poems onto the soap? It would be both elegant and unique. If we made a set, people could collect and play with it."

Wang Xifeng nodded repeatedly, her eyes sparkling with excitement: "Brilliant! She's definitely one of our family's girls; she's got so many ideas!"

She immediately ordered someone to bring paper and pen, and wrote down her sisters' suggestions one by one.

At this moment, Baochai also arrived gracefully. She picked up a bar of soap, sniffed it gently, and smiled, "Feng'er, if we added some medicinal herbs to this soap, such as mint or jasmine, it could both cleanse the skin and refresh the mind. Wouldn't that be killing two birds with one stone?"

Wang Xifeng clapped her hands and praised, "Baochai is indeed knowledgeable! This is a good idea. I will have someone find some top-quality medicinal herbs as soon as possible."

Everyone chimed in, creating a lively atmosphere.

Even the usually taciturn Li Wan couldn't help but interject: "If we were to make two types of soap, one for men and one for women, with the men's version having a pine and cypress scent and the other for women having a floral scent, it might better cater to different people's preferences."

Wang Xifeng was overjoyed and laughed, "I have truly benefited greatly today! Once this deal is done, I will definitely thank you properly!"

The group discussed the matter enthusiastically until sunset, unaware of the passage of time.
