Standalone Birdh House Collapse 独立式燕屋倒塌

Do you want your birdhouse to be collapse when it is fully occupied ???

And your long terms investment will also collapse !!!

My question is :

Can I sign a contract agreement before you starting to build a Bird House ???.

当燕屋有收成时，倒塌了怎么办？？？

到时您的长期投资计划也跟着倒塌了！！！

我的问题是：

i) 可以签署一份保证合约吗？
