Cute Kitten Zhou Ji 600 words
Cute Kitten Cats were very cute little animals. They were clever and lively, bringing a lot of fun to people's lives. I have a kitten at home. It looks very interesting. Its head was round like a fluffy ball. The fur was black and white. The white fur was as pure as the first snow in winter, and the black part was like ink that had been dyed, forming a unique pattern. Its eyes were big and bright, like two crystal clear emeralds, shining with a mysterious light in the darkness. Its ears were always alert, and it could capture even the slightest sound. The kitten's nose was small and pink, and it was very sensitive to the surrounding smells. There were a few long and thin whiskers on its mouth. These whiskers were its " detection artifacts " that helped it sense the width of its surroundings. Kitten's personality was very changeable. Sometimes, it would be especially quiet. It would find a warm and comfortable corner, curl up into a ball, and then close its eyes. It would sleep for a few hours, just like a quiet little furball. But sometimes it was particularly active, running around the house, jumping from room to room, as if it had endless energy. It was curious about everything around it. A small ball of paper or a small rope could become its toy and it was having a great time playing with it. It was also very playful. Once, I threw a little furball out, and it immediately chased after it. It kept playing with the little furball with its claws. It threw the ball here and there. From time to time, it would pick up the ball with its mouth and run away while shaking its head. However, when it discovered that there were mice around, it would become particularly dutiful. It would carefully approach the place where the mouse appeared, its eyes staring closely, and its body was very low. Once the mouse appeared, it would pounce at a very fast speed, grab the mouse with its sharp claws, and then take it to a corner to enjoy its " trophy." The existence of kittens has brought a lot of joy to my family. It was like a little angel. Although it would sometimes be mischievous, such as messing up my wool ball, its cute appearance made people unable to get angry at all. I love my kitten. It is an indispensable companion in my life.
The Ranking of Wealth and Riches
There was no clear and unified ranking of the rich and noble in Ziwei Dou Shu. A good combination of husband and wife's official salary palace was a manifestation of the pattern of wealth. For example, when the husband and wife's official salary palace had such patterns as the intersection of salary and horse, the sun and moon, the greed of power, the Ziwei Tianfu, etc., it was easy for the master to succeed in his career. If the male's life was good, he might even marry an excellent woman and make a fortune after marriage. As long as there were any of the six auspicious stars (Wenchang, Wenqu, Zuo Fu, You Bi, Tian Kui, Tian Yue) in the Life Palace, it was also related to wealth. Wenchang and Wenqu in the Life Palace represented good reading luck and social status; Zuo Fu and Youbi in the Life Palace were called "Dafu", representing power; Tian Kui and Tian Yue in the Life Palace were called "Dagui", and there would be noble people to help in the face of setbacks. The wealth patterns related to those who sat on Tianliang Star were Yangliang Changlu Ge (Sunshine Thunder Gate), Jiyue Tongliang Ge, Jiliang Jiahui, etc. If the migration palace had Tianliang Hualu, the ancients said that they could become rich merchants. Those who entered the Life Palace on the Heavenly Mansion Planet would receive help from many noble people in their lives. This could also be seen as a manifestation of the rich and noble situation. Although Lu Ma Jiao Chi Ge and other things received much attention, whether it brought great wealth or not was still affected by factors such as luck. Moreover, different patterns had different effects on wealth under different life situations and palace combinations, so it was difficult to carry out a strict ranking.
