    A total of 34 Chinese cities with a combined population of nearly 300 million took park in a pet adoption day at the weekend, promoting the adoption of rescued stray (流浪的)animals.

    The live broadcast of China Pet Adoption Day events in Shanghai, Beijing, Chengdu, Guangzhou, Hangzhou, Nanjin, Qingdao, Tianjin and Xi'an was watched by 562,000 people.

    From Urumqi in the far northwest to Fuzhou on the southeast coast, people gathered to raise awareness of animal care and to help stray find loving homes.

    Sun Quanhui, manager and senior adviser of World Animal Protection, said, “Planet Earth is not only home to humanity but also a home that we share with other animals. It is mankind's duty and important to treat animals kindly in a civilized society.”

    As China's population becomes richer, pet ownership has increased rapidly, but problems, such as pet abandonment and cruelty, are also growing.

    In recent years, more and more adoption events have taken place all over the country, which indicates an awakening of the Chinese public consciousness to animal protection.

    “Adopting a pet instead of buying one has been gaining a wider acceptance.”

    American Edward Dumpe, who has been working on designs for stray animal shelters in Beijing, said, “It surely sounds super sweet and I have no doubt that it must have been the result of great efforts.”

    “I think it is a good step in the right direction, and should be taken as evidence that Chinese society is becoming more aware of stray animals who should be taken care of and treated with respect.”

    In real life, “Rabbit-eating Carrot” is fashion designer who has created clothes embroidered(刺绣)with slogans(口号)such has “Please adopt a pet” and images of her cats, with all earnings going to the Qiming Small Animal Protection Center in Sichuan Province.

    “I didn't know that there were events like this in China. This is fantastic. Impressive.” Said George Philippe, a french living in Beijing and father of two, at an event in the capital.

赵城虎

    赵城妪,年七十余,止一子。一日入山,为虎所噬。妪悲痛,几不欲活,号啼而诉于宰。宰笑曰:“虎何可官法制之乎?”妪愈号啕,不能制之。宰叱之,亦不畏惧。又怜其老,不忍加威怒,遂诺为捉虎。媪伏不去,必待勾牒出,肯行。宰无奈之,即问诸役,谁能往者。一隶名李能,醺醉,诣座下,自言:“能之。”持牒下,妪始去。隶醒悔之,犹谓宰之伪局,姑以解妪扰耳,因亦不甚为意。持牒报缴,宰怒曰:“固言能之,何容复悔?”隶窘甚,请牒猎户,宰从之。

    隶集猎人,日夜伏山谷,冀得一虎,庶可塞责。月余,受杖数百,冤苦控。遂诣东郭岳庙,跪而祝之,哭失声。无何,一虎自外来,隶错愕,恐被咥噬,虎入,殊不他顾,蹲立门中。隶祝曰:“如杀某子者尔也,其俯听吾缚。”遂出缧索絷虎项,虎帖耳受缚。牵达县署,宰问虎曰:“某子尔噬之耶?”虎之。宰曰:“杀人者死,古之定律。且妪止一子,尔杀之,彼残年垂尽,何以生活?倘尔能为若子也,我将赦之。”虎又颔之,乃释缚令去。

    媪方怨宰之不杀虎以偿子也,迟旦,启扉,则有死鹿,妪其肉革,用以资度。自是为常,时衔金帛掷庭中。妪从此致丰裕,奉养过其子。心窃德虎。虎来,时卧檐下,竟日不去。人畜相安,各无猜忌。数年,妪死,虎来吼堂中。妪素所积,绰可营葬,族人共瘗之。坟垒方成,虎骤奔来,宾客尽逃。虎直赴冢前,嗥鸣雷动,良久去。土人立“义虎祠”东郊,至今犹存。
