永昌隆是澳門碩果僅存的舊式糧油雜貨舖，堅守傳統經營逾半世紀，專賣精選散裝米和國內外優質糧油乾貨。老闆娘「貓姨」對每位街坊的喜好了然於心，「大發、細發」兩隻貓咪亦深得街坊喜愛，永昌隆老字號，多年來承載著街坊鄰里的人情味。

貓咪的職責主要是為雜貨鋪捉老鼠，因為形象討喜，久而久之卻變鋪頭的吉祥物。設計師為突顯貓咪和貨品的微妙關係設計了一系列圖案，應用在紙袋、糧油雜貨等包裝上，並進行外牆塗鴉，為老店新添萌點。具港澳特色的書法字和逗趣的圖案相結合，傳遞老店在街坊心目中可愛親切的形象。

Wing Cheong Long Trading is one of the few traditional rice shops that still left in Macao, specializing in selling selected rice and high-quality grain and oil groceries from local and abroad. Auntie Kitty, the boss’s wife always keeps customers preferences top of mind and her cats, “Tai Fat and Sai Fat”, are very popular in the neighborhood. The time-honored brand shop followed the traditional operation mode for over half of a century and has overflowed with human warmth through the years.

Since the cats are cute and good at catching rats in the shop, they gradually become the mascots of the shop. In order to highlight the subtle relationship between foodstuffs and the cats, a series of graphics were designed and applied to the doggy bag and package design of the foodstuffs. Besides, the designer would paint graffiti to make the old shop more adorable as well. With the combination of traditional calligraphy characters and funny patterns, the designer is successful to present the friendliness and loveliness of Wing Cheong Long Trading to all customers.
