下面是一封悼念业务伙伴的慰问信，可供参考：

Dear President Anderson

We were distressed to read in the Times this morning that your Chairman, Mr. Yonga had passed away and I am writing at once to express our deep sympathy on behalf of my colleagues.

I had the privilege of knowing Mr. Yonga for many years and always regarded him as a personal friend. By his untimely passing our industry has lost one of the ablest leaders. We at the representative office in London recall his many kindnesses and the pleasure of doing business together with him. Mr. Yonga will be greatly missed by all of us who have known him and worked with him in building a better community between our two businesses.

Please accept our deepest sympathy and convey our best wishes to Lady Yonga and her family.

Kevin Smith
Chief Representative
London Office
L&L Industry Co. Ltd.
