It's always a trouble to express what you know in another language. Cow ticks, for instance, I am so familiar with this parasite, when I started herd my buffalo as early as I was seven. I pressed my face on the buffalo's large stomach while it was grazing on the grass. I was so fond of doing this that a tick went into my ear, and died there. several weeks later, I felt uncomfortable in my ear and went to barber, he dropped some vegetable oil into my ear and picked it out using an ear picker.
But I never know how to say in Mandarin, that is different with my mother tongue which is also a Chinese dialect. When I moved to England, this creature always sneaks through my thought, keeps me wondering how to say it in English.
To day I went to shopping, read a leaflet from Sainsbury's Pharmacy counter, which tells you how to treat pet lice,flea and ticks. Wow!
