〃How　are　you；　General？〃　said　Lu　Su。

〃My　heart　pains　me。　Every　now　and　again　I　feel　faint　and　dizzy。〃

〃Have　you　taken　any　remedies？〃

〃My　gorge　rises　at　the　thought。　I　could　not。〃

〃I　saw　Zhuge　Liang　just　now；　and　he　says　he　could　heal　you。　He　is　just　outside；　and　I　will　call　him　if　you　like。〃

〃Ask　him　to　e　in。〃

Zhou　Yu　bade　his　servants　help　him　to　a　sitting　position；　and　Zhuge　Liang　entered。

〃I　have　not　seen　you　for　days；〃　said　Zhuge　Liang。　〃How　could　I　guess　that　you　were　unwell？〃

〃How　can　anyone　feel　secure？　We　are　constantly　the　playthings　of　luck；　good　or　bad。〃

〃Yes。　Heaven's　winds　and　clouds　are　not　to　be　measured。　No　one　can　reckon　their　ings　and　goings；　can　they？〃

Zhou　Yu　turned　pale　and　a　low　groan　escaped　him；　while　his　visitor　went　on；　〃You　feel　depressed；　do　you　not？　As　though　troubles　were　piling　up　in　your　heart？〃

〃I　have　taken　a　cooling　draught；　but　it　has　done　no　good。〃

〃You　must　get　the　humors　into　good　order　before　the　drugs　will　have　any　effect。〃

Zhou　Yu　began　to　think　Zhuge　Liang　knew　what　was　really　the　matter　and　resolved　to　test　him。

〃What　should　be　taken　to　produce　a　favorable　temper？〃　said　Zhou　Yu。

〃I　know　one　means　of　producing　a　favorable　temper；〃　replied　Zhuge　Liang。

〃I　wish　you　would　tell　me。〃

Zhuge　Liang　got　out　writing　materials；　sent　away　the　servants；　and　then　wrote　a　few　words：

〃To　defeat　Cao　Cao

You　have　to　use　fire；

All　are　in　your　wish；

But　wind　from　the　east。〃

This　he　gave　to　the　sick　general；　saying；　〃That　is　the　origin　of　your　illness。〃

Zhou　Yu　rea
