Episode 4 recap: Wang Hong created a savings plan.

Liu Mei Qin has been closely watching Lv Xiang. When Lv Xiang is working during the day, Liu Mei Qin is satisfied because this allows Gu Xiao Meng to get good rest. They have stipulated that Lv Xiang can only smoke three cigarettes a day. Lv Xiang could not stand it and planned to sneak out to smoke, but was discovered again by Liu Mei Qin. Lv Zhi Gao and Wang Hong also agreed with Liu Mei Qin's view and did not allow Lv Xiang to smoke. Lv Xiang had no choice but to put down the cigarette as required, but he had a backup stash of cigarettes hidden in the hallway outside.

Wang Hong could not find any information online about the impact of coffee on sperm quality, and thought that Liu Mei Qin's plan might be specifically targeted at Lv Xiang. However, Lv Zhi Gao thought the health plan was quite good. Wang Hong did not say much more, but felt there were many wasteful phenomena in the household, and he also needed to make a plan after returning home, but he had trouble writing the word "punishment" and specially asked Lv Zhi Gao for advice.

When Gu Xiao Meng just returned, Lv Xiang was waiting for her in the hallway, eagerly telling her that he had shown Peng Fei's film to a director, who was very satisfied and praised the high school student for making a film with emotion. This also made Gu Xiao Meng very happy, at least the effort was not in vain.

Lv Xiang complained to Gu Xiao Meng that today Liu Mei Qin barged into the room without knocking, but he still needs to continue to endure. The two encouraged each other at the door. Wang Hong brought out his proposed savings plan, but it was opposed by everyone, who felt they were not wasteful. However, Wang Hong listed the waste of each person, believing that Gu Xiao Song never unplugged the power cord after charging, Liu Mei Qin took three-hour showers, and Gu Xiao Meng turned on all the lights as soon as it got dark - these were all examples of wasteful details.

Liu Mei Qin was speechless for a moment. Wang Hong believed that these small areas of waste would exceed 2,000 yuan a year. Gu Xiao Meng proposed a vote, and only Wang Hong raised his hand. Wang Hong kept asking Lv Zhi Gao to raise his hand, and Lv Zhi Gao reluctantly did so. Liu Mei Qin, who had been caught, did not want to raise her hand but ended up doing so. In the end, Wang Hong successfully won the plan, and Gu Xiao Meng had to sigh that the old spice is the sharpest.

Gu Xiao Meng was hot and had a small fan to cool herself, because the air conditioning could not be turned on now that the hot weather had arrived. To be able to access the internet, Lv Xiang had to buy the wireless password from the upstairs neighbor, demonstrating that there is a policy above and a countermeasure below.

Gu Xiao Meng told Peng Fei the director's evaluation of his film, and also discovered a problem with Peng Fei's test paper - he got the difficult questions right but made mistakes on the easier ones, indicating that he had intentionally answered incorrectly. She wanted to know what Peng Fei was thinking, and he silently lowered his head, knowing that Gu Xiao Meng had seen through him.

While Liu Mei Qin and Wang Hong were washing dishes in the kitchen, they discussed new concepts for elderly care. Liu Mei Qin deliberately said that if she had a partner, she would travel all over the country, and when she was old, she would live in a nursing home and have her ashes scattered in the sea, so she wouldn't have to sweep the grave. In fact, she also did not want Lv Zhi Gao's couple to come and live with Gu Xiao Meng when they were old.

Wang Hong, however, considers himself a northerner, different from the southerners. When he heard that Gu Xiao Meng, who did not use shower water to flush the toilet, he was a bit unhappy. Gu Xiao Meng had no choice but to lie and claim that the shower water had run out, and when Wang Hong wasn't looking, she secretly poured out the water in the bucket.

In the evening, when Lv Xiang was using the computer, he found that the upstairs internet was down, but considering it was late at night, he couldn't go bother the neighbors. Gu Xiao Meng wanted to secretly turn on the wireless network at home, but was discovered by Liu Mei Qin, and the mother and daughter got into another argument, which brought the whole family out to the living room. Wang Hong also felt that they were being too harsh on Lv Xiang, and the two mothers-in-law also argued for a while, making Wang Hong almost faint from anger.

Gu Xiao Meng apologized to her mother and blamed herself for not controlling her emotions well today. After comforting Wang Hong, Lv Xiang went to the room to comfort his wife, knowing she was already very tired, and actively proposed that the two of them go out for a romantic weekend. The time they spent alone together was happy and sweet, and their world was full of love.

Wang Hong and Liu Mei Qin went to the supermarket to buy groceries together. Liu Mei Qin proactively apologized for her bad attitude yesterday, and also gave Wang Hong a physical examination card, wanting to take her for a checkup. Wang Hong felt a bit awkward and wanted to refuse, but Liu Mei Qin insisted on taking her, so Wang Hong reluctantly agreed.

Gu Xiao Meng found that her parents had planted garlic chives in the pots at home, thinking it was economical and delicious, and that they could continue planting next year. Hearing the words "next year", Gu Xiao Meng was shocked. Kanglikang had given Lv Xiang an opportunity to earn money, but Lv Xiang was still short by over a million. The money from selling the house was only 800,000, and he hoped that his partner Nanke could also help, but Nanke expressed difficulty, as his wife was pregnant with their second child.

Gu Xiao Meng heard Wang Hong and Lv Zhi Gao nagging about having a child again, and finally couldn't hold back her anger. She emphasized that having a child was their business, and Gu Xiao Meng had a premonition that if they forced them to have a child, they would never give up.

Lv Xiang saw that Gu Xiao Meng's expression didn't look good, so he quickly went into the room to comfort her. Gu Xiao Meng seemed to see a glimpse of her future life. At night, Gu Xiao Meng had a dream where she just entered the house and her parents brought her a birthday cake and sang a birthday song, a seemingly happy scene. But when Gu Xiao Meng blew out the candles, she found that she was 120 years old. When she looked up, her parents had white hair and said they had lived here for 99 years and would live for another 100 years, which frightened Gu Xiao Meng and woke her from the nightmare.
